for those of you who commute on your bikes, what kind of boots do you ride in?
Nice day for a ride

USMC RAT boot.
I still don't have boots.
Some black Sedici ADVboots. The were nice until my highside compromised the waterproof seal on the right boot. They're fine in the dry though.
what front fender is that?
I wear my work boots on the average day. I wear Dainese TRQ Tour's when I'm not commuting or just heading to the cafe.

For litrebikes: vtwin or inline 4?
And I'm in Italy. That doesn't mean I ride with my bike to a bar, trying to be a cool kid as hard as I can.
Not that I could anyway with that shitty winter jacket I use.
>For litrebikes: vtwin or inline 4?
Seriously nigger?
So yesterday I found out a riding buddy of mine was hoonin it up on a road that contains an elementary school, middle school, and community college all on the same strip of road, with 3 lanes on each side with a concrete median in the center.
It's reported that he was doing a wheelie, lost control, and the bike managed to jump the curb striking a 15 year old girl who apparently broke both her ankles and her arm.
On a scale of 1 to Pornhub, how fucked is he?
He was arrested on site for wreckless driving.
>pic related, it was sent it to me by another riding buddy who wasn't with him but was in the area.
4 cylinders.
What a cunt. Completely fucked, he's getting jail time.
Efukt
V4. Duh.
>tfw no bike with RC51 looks but I4 power
Damn, and I thought vtwins were supposed to make lower rpm torque even if they dont make quite as much power.
The RC51 gets walked by the blade until redline, and then the blade keeps on going... literally has nothing on the 4 cylinder.
>it's okay to ride recklessly, you will only endanger yourself
>/dbt/ will try to find a way to defend this
Get fucked, hooligans, I hope you stupid fucks will end down a mountain before actually hurting a poor kid, like this one.
>implying
There's an etiquette to being a suicidal hoon. Generally not doing stupid shit around schools is one of those things.
I ride to two different cafes here in Iowa because I like the food and the coffee. I can't into the bar scene, but that's because I'm halfway to NEET status. I certainly don't look cool in my dorky Cortech gear but IFGAF; it's comfy.
They can slap him with anything from assault with a deadly weapon to child abuse and gross negligence leading to injury.
Are you going to spend all your time near redline? If so inline 4. If not V-twin
But if it's a V-Twin like my V-Stronk, the former God's Sake, get a PowerCommander to smooth it out. It's not Harley-tier but still.
>aussies
>hooning
>etiquette
Don't even try, please.
>thought vtwins were supposed to make lower rpm torque
They do that through displacement most of the time.
Consider the 959 Panigale vs Aprilia RSV4RR.
The Aprilia makes much much more power and more peak torque with just 40cc more displacement. The Ducati has a slight edge on low-end torque HOWEVER because the redline is significantly lower, it is likely geared longer, so wheel torque will be less at any road speed.
4 cylinders have flatter torque curves and more linear power delivery which is more predictable.
Vtwins a shit.

Common sense shit. Squids don't into common sense tho.
He's right. if you're going to act a fool you do so somewhere you're not going to hurt anyone else.
Hooning near a school or in traffic is full retard.
Hooning on an empty back road is something else entirely.
>hooligan

You guys are pathetic, I want you to know that.
so riding your bike to a business makes you a tryhard?
Your complete lack of argument betrays your shoddy position.
Try harder fag.
>4 cylinders have flatter torque curves
Kek, where do you guys get this stuff
>That low rpm sine wave
I always figured the V-strom would have a pretty clean power curve
>Kek, where do you guys get this stuff
Reality.
>That low rpm sine wave
Lets play spot the Vtwins.
Which torque curves have the largest difference between when they sign on, hit peak torque, and sign off?
I.E.the ones with the least flat toque delivery.
>Spoiler:
>It's the Vtwins
>the ones with the highest torque have the highest displacements by over 200ccs
Yeah man real flat power curve you got there
My argument is that if you drive dangerously on the road shit is bound to happen, not only to you but also to other people. As you can see from what happened to that user's friend.
Meanwhile your argument is
>dude just be careful while you wheely and do other stupid dangerous stuff
If you can't see the oxymoron you're an idiot who shouldn't be allowed to ride motorcycles.
So I'm guessing you sit in the center of your lane, never go beyond 5mph over the speed limit, and never lean more than 1 degree because "that's stupid and dangerous!"
Driving dangerously and having a complete disregard for the safety of others are two different things if you save the dangerous driving to places where you only jeopardize your life.
I want reddit to leave.
That is a flat as shit torque curve retard. You think ANY engine isn't going to ahve some form of torque ""curve""?
Look at the "flat" ducati Vtwin torque curve shown here:
Then tell me that R1 dyno sheet isn't flat.
Man wtf is Ducati doing

Lemmings squeezy.
>My argument is that if you drive dangerously on the road shit is bound to happen
This is a given.
>not only to you but also to other people.
If you don't hoon around other people, how is your hooning going to hurt anyone?
>As you can see from what happened to that user's friend.
He was hooning like an idiot in front of a school with kids around like an idiot. That's the point.
>dude just be careful while you wheely and do other stupid dangerous stuff
No, my argument is if you're going to do dangerous things on a motorcycle, you do it away from others so if you do fuck up, you hurt yourself and no one else.
>muh superquadro
they can't make competetively powerful twins without ridiculously oversquaring their engines, resulting in gutless engines low-down, unless displacement is increased beyond any comparison (hurrdurr we can make a 200hp engine like BMW but only if we use 30% more displacement)
Compare the R1 to the RC8 in your graph. That's the best comparison considering they were probably run on the same dyno with a similar environment. I won't apoligize for Ducati's curve there I don't know how you lose that much torque down low with a large twin
Okay.
Looking at the power curves. the R1 has a much more linear delivery and a nice plateu near peak power up top, meaning it can accelerate at near peak power for longer than the RC8R which hits it's peak power and fuel cut immediately after.
The RC8R also hits a big midrange surge but then starts to flatline at ~7krpm until it squeeks out it's peak power and signs off immediately after.
R1 has a mostly linear ramp up of power until 10,000rpm until it levels off and holds near peak power for about 3000rpm.
This argument again.
Riding dangerously doesn't equal riding spirited.
Given how stupid hooligans are their judgement about "this only poses a danger to myself!" has no value at all.
>hooning like an idiot
Only way to hoone, otherwise it wouldn't be hooning.
If you wanna do this shit you do it on the track or places for stuntmen, but then again you wouldn't be a hooligan anymore and that's the only thing you obviously care about.
>Only way to hoone, otherwise it wouldn't be hooning.
Your argument is that you're going to hurt other people.
This argument fails because you can "hoon like an idiot" by yourself with no one else around. In which case you are only endangering yourself and your property and your entire "B-but you'll hurt someone else!" argument completely falls apart.
Thus there is "hooning etiquette". If you're going to do it, don't do it around other people or in situations people are likely to be, endanger only yourself and your own shit.
If you can't understand this very basic concept you're a fucking retard.
>If you wanna do this shit you do it on the track or places for stuntmen
>go to a race track if you want to pull a wheelie
>spirited riding
>not dangerous
AYY LMAO
>Given how stupid hooligans are their judgement about "this only poses a danger to myself!" has no value at all.
Your simplistic one-size-fits-all assessment of people who would pull a wheely and baseless generalizations show you're grasping for straws to pigeon hole the argument in your favor.
It is entirely reasonable and likely that there are people who enjoy hooning and are smart enough to hoon responsibly in situations where they will not hurt other people.
In my generation of V-Stronk it's a bit rough below 3,500 RPM or so because Suzuki tuned it pretty lean in a certain band for economy/emissions reasons. A PC fattens up that part of the range (and a little bit elsewhere) and makes for a smoother experience. I haven't invested in one yet, but all the posts I've read about rave about the smoothness.
ITT: guys who don't know how dynos work
These are all measurements taken by wotting in 6th gear
If you don't take into account the lower gearing of SS i4s it's useless
It's clear that more cylinders are better in a race environment, but the argument here is that v2s are better for city riding
When you're not wotting until redline
In 6th gear
An overdrive gear
>This argument fails because you can "hoon like an idiot" by yourself with no one else around
>you can hoon by yourself
Yeah but will you? Is your judgement, the judgement of a retard that behaves like this on public roads willingly, a quality one?
>likely
Lmao.
What a retard.
>or places for stuntmen
Reading only the parts that you want, uh?
Depends on your skills.
>hoon responsibly
This is my favourite one this far.
Please go kill yourselves on a mountain road, I have no desire to continue this farce.
>or places for stuntmen
Yeah because there are motorcycle stunt parks all over the place, right?
>Depends on your skills.
So it's basically hooning then? If you're shit you will lose control of your bike and possibly send it flying into someone.
>a retard that behaves like this on public roads
Rich coming from the guy who does spirited riding on public roads. Go to a track if you want to push yourself and your bike.
>If you can't see the oxymoron you're an idiot who shouldn't be allowed to ride motorcycles.
Most dynos (all of the ones plotted here) are plotted over RPM as the 'time' component. This effectively invalidates any differences in final ratio between the bikes.
The story is different if you plot wheel speed at the 'time' component.
>but the argument here is that v2s are better for city riding
No, literally no one has made that argument here.
>When you're not wotting until redline
The argument was that inline 4's offer a flatter torque curve and a more linear power delivery, which is true. linear power delivery is less likely to catch you off guard or surprise you in a turn.
On the other hand, overly strong midrange torque and sudden increases in torque/power do catch you out and are more likely to overwhelm rear wheel traction.
>In 6th gear
>An overdrive gear
Pretty much no sport bikes have an overdrive 6th gear. 4 cylinder sport bikes typically ahve around a 1.2:1 6th gear.
And your argument further doesn't make sense because a vtwin sportbike with it's shorter redlines would require overall, taller gearing per gear. As a general rule if a bike has a 30% lower redline it will typically have around 30% taller gearing per gear to compensate for road speed, and thus will effectively have 30% LESS torque available in a given gear. Which means a Vtwins torque advantage disappears for any given speed unless it makes more than 30% torque than an equivalent 4 cylinder at a given read speed in a given gear.
This guy speaks the truth.
>Yeah but will you?
You can, and many do. This invalidates your argument that "any" hooning is going to hurt someone else and that there is no etiquette to it.
>the judgement of a retard that behaves like this on public roads willingly, a quality one?
Nothing suggest it is impossible to have good judgement and enjoy hooning in a responsible manner where you only endanger yourself.
You are trying to fabricate a false dichotomy where anyone who is going to hoon lacks the judgement to hoon responsibly and with other people's safety in mind. This argument, logically, doesn't hold up. you have not proven anything to that effect and you are simply spraying your biased and generalized opinions with no basis.
>Please go kill yourselves on a mountain road, I have no desire to continue this farce.
Someone killing themselves on a back road would not prove your argument as they would likely only hurt themselves because they were hooning responsibly.
Enjoy riding a motorcycle without ever actually enjoying it to it's fullest because you think it's unsafe to do anything other than peter along a the speed limit.
>Yeah because there are motorcycle stunt parks all over the place, right?
You don't have to wheelie, you know that, right?
You could, god forbid, have fun riding the bike.
>So it's basically hooning then? If you're shit you will lose control of your bike and possibly send it flying into someone.
Yeah, except there's a thing called "riding license" that should avoid that.
Never said I do that, I said there's a difference.
>Someone killing themselves on a back road would not prove your argument
No but it would make the world a better and safer place for everyone else.
>And your argument further doesn't make sense because a vtwin sportbike with it's shorter redlines would require overall, taller gearing per gear. As a general rule if a bike has a 30% lower redline it will typically have around 30% taller gearing per gear to compensate for road speed, and thus will effectively have 30% LESS torque available in a given gear. Which means a Vtwins torque advantage disappears for any given speed unless it makes more than 30% torque than an equivalent 4 cylinder at a given read speed in a given gear.
I think I understand that but my brain hurts from trying.
...
>and safer place for everyone else.
This is the premise of your argument but logically it doesn't hold up and you have not demonstrated it.
False dichotomies are failed arguments.
Lost my license for 6 months.
>I think it's safe so it's safe
Yeah, tell me about it.
I never claimed anything was safe.
I stated the simple reality that if you don't hoon around people you can't hurt other people. Thus is is possible to hoon responsibly, conform to a basic etiquette, and only endanger yourself and your own possessions.
You claim otherwise and fail a basic logical argument.
1. You can't know if you're alone on the road
2. You can't predict what will happen if you lose control
Note how I used the form "can't", not the one "don't".
how
>have fun riding the bike
But they do? They just do it with one wheel off the ground sometimes.
>a thing called "riding license" that should avoid that.
Having a motorcycle license doesn't make you a good rider and it sure as hell doesn't mean you're capable of doing any spirited riding safely.
>1. You can't know if you're alone on the road
This is false. Simple eyesight can tell you whether you are alone on a road. People and cars are not invisible.
>2. You can't predict what will happen if you lose control
You can't know exactly what will happen, but you can be positively sure your bike will not fly 2 miles into the next town and land on a toddler.

That's why I said "should".
Do you realize they're called accidents for a reason, right?
Speeding offences lead to good behaviour period, neg riding charge breached that. Selling my bike and going travelling for 6 months throughout the suspension
TRAFFIC COLLISIONS
What bike?
>Welcome to the Harley lifestyle
No, I used accident on purpose.
He thinks he can predict while he can't. If you're doing something extreme you can't avoid accidents.
1971 CT90, just rebuilt the engine a few months back. Not sure if it's because I decided to use the old head as is or if I just rode it too hard.
>Do you realize they're called accidents for a reason, right?
They are called "accidents" because the term does not assign blame to any parties and is used as a means for explaining an incident without attributing fault to oneself or others.
This is irrelevant to the current discussion however.
If done responsibly you can hoon without the possibility of "accidentally" landing your bike on a toddler by choosing your location carefully, prerunning the area, and ensuring you have adequate sight lines.
I always feel like you should be smarter than this but you never are. Like you should know that flat torque curves are about more than just the cylinder count and a flat torque curve has as much to do with bore/stroke as it does with the fueling and ignition timing.
I4s can be just as linear as V-twins and generally are more linear when it comes to performance models, a lot of v-twins are tuned to be flat which is why they are, when I4 engines are designed to be flat they are.
You're posting engines from 1000cc superbikes, but you won't find a flat torque curve on a superbike v-twin either, have a look at a dyno from a panigale.
