Hi everyone,

Does anyone try to measure maximum lean angle of R1 2015 within frame slider?
I have used iphone app and speedangle, it shows about 61 degrees when I lay the bike on the ground.

And can I ask for the lean angle that I have archived in below picture, does anyone try to measure the similar?

Thank you!

Picture doesn’t work for me. The maximum lean angle depends on tires, and how balsy you are. If you’re street riding, you aren’t going to come close to max lean angle unless you’re in the mountains, and even then prob not.

nope never measured. Guess the only one answering your question. :icon_frown:

number one rule of physics.. a body in motion wants to stay in motion.

bikes are faster when ridden as straight "as possible", higher corner speeds result from 'less' of a lean angle.
as posted above, drive out of the corner is improved as well. Its likely less obvious with all that electronic
circuitry going on in modern bikes. Most folks, no offense of course, sacrifice body positioning for lean angle.
result is lower cornering speed.


now, that being said i do think its a good idea to gauge the limits of said bike as you may have
that ohh shit moment and leaning the fvck out of it may very well save your arse :fact

OP i did see said info posted online recently, not on here. I didnt write it down, but it was less than Marquez's :yesnod :lol

i dont believe the S1kRRs max is 64 degrees.. thats definitely bullshit, its still just a roadbike :no

IIRC they've mentioned it at some point in the past.

interestingly enough i just came across an article discussing the 2019 WSBK, the V4 Ducati specifically..


Old dog, new tricks

There’s also a reason why we don’t see the Ducati riders riding with the same style as the rookie: the Pirelli tires. The Italian rubber needs to be ridden in a certain way. Typically that’s with as little angle as possible. It’s about getting the bike upright as soon as you can. Whereas most riders will try to carry that corner speed, the fastest riders in WorldSBK have always tried to get the bike stopped and shot out of the corner as quickly as they can by spending as little time on the angle as possible.


also, completely random image, but still i find this one very cool :dunno

This also depends on the bike... ride a ZX10R and yeah, point and shoot all you can or you're screwed. R1, not so much. In fact, if you're coming from a 600, the R1 will let you get away with a lot if you keep using your old 600 lines. Is it the fastest way around? Nope. But on a ZX10 or S1000RR you'd be a sitting duck if you tried it.


Ps: I'm talking stock bikes that have been race prepp'd. WSBK is whole different thing and despite new regs and etc, those bikes don't have a lot in common with what ppl here will ride in their lifetime.

Two riders going the same speed through a turn, one leaned over more means the other rider (less lean) is more skilled.
this is something you can sometimes see as well, even without slow motion takes..

one things that keeps sticking with me is that those cameras they use these days are fvcking amazing..
so many frames per second to play with. We forget that for a lot of those really deep lean angle curves / shots
we see on screen, its only for a split few seconds where a rider is leaning so far over.

Also, GP bikes are designed completely different from road bikes, there really isnt much comparison :no

I often see a hell of a lot more trail-braking, kicking the rear around so you square off a corner and blast off than actual 'look at me, i'm leaning' scenarios.

Guess who won this race and most of the races we competed together in? Lean angle isn't everything. Its something to be managed to increase safety and speed.





Answer is 93... maybe not for long, I think 87 needs better tires. 87 is my favorite racer out there though. I'm a huge fan :)

i think you're splitting hairs honestly.. :dunno

just because there may be no point to this or that based on that or the other, in your opinion that is;
does not mean it is UNOBTANIUM.. All it means you yourself have decided the inve$tment is not worth-while
based on its 'expected return'. Maybe you'll make a horrible decision and bin the stupid thing thanks to your
limited skill, or maybe you'll actually learn to ride within its 'limits'..

for the most part you're still purely describing custom one off machined parts.. you may think its out of your reach financially,
but if you have access to a shop and a skilled machinist, builder etc. it has very little to do with weather you have the skill or
not to utilize it.. You literally can slap just about anything you want on your bike. It all depends on how creative you are at
that point. Last time i checked there's plenty of 'triple-clamp' manufacturers out there doing some pretty damn impressive R&D.
But of course, its a business and the intended buyer is a GROUP of riders, not ONE dude with A race bike and his 'back-up' bike.
So you're 10 lbs lighter, heavier or a few inches taller.. NO sir, you're not allowed to use this product, you'll never see the true
benefits.. Jesus, put the calculator down already, its not all about 'numbers' :sneaky

i think its funny people truly think none of that shit is available period, and yet you see forum members
bragging about one off parts they're lucky enough to have in their possession. Once a new model bike
is out, race teams couldnt care less who has what, and which team donated it. :no

i'm talking about parts DIRECT from the RACE team who utilized it for its intended purpose.
And possibly had a hand in its design, production, testing, etc. Money cant buy you happiness
but you can still blow your load on race-bike porn and thats pretty damn close.

so where is this idea that NOBODY, EVER, IN THEIR LIFETIME.. will ever see?? :hammer:

plenty of motorcycle magazine editors, creative writers have been granted a chance to toss a leg
over a true WSBK beauty. Do you really intend to 'call them out' for being inferior to such a bike.?

i have a real problem with folks belittling themselves and their riding ability. If you want to consider yourself
a 'mere-mortal' thats entirely up to you. You cannot expect every single other rider in the world to hold
themselves to the same silly mental limitations.

I'm not even gonna go into the rest as I feel I've discussed that enough but the msg just didn't get through...

But if you HONESTLY believe you can ride well enough that you need WSBK parts then you're either doing AMA or some other racing category of that level and winning LOTS or you're just out of your depth here and you're one of those rider who will either spend a bomb chasing improvements on the bike instead of your riding or you'll get really hurt at some stage. Maybe both. So here's hoping your last name is Hayden or Elias or even Bautista.

Now, I'm actually not a bad amateur racer even if I say so myself but the difference between even a back marker professional rider and an amazing amateur racer is huge. I've had the pleasure of sharing the track with some proper fast guys, WSS/WSBK/AMA current and ex riders and you just can't compare their abilities and the way they ride to a regular joe like myself.

So when I read you saying "You cannot expect every single other rider in the world to hold themselves to the same silly mental limitations." I think you're right. Not every single rider. But 99.99999% of them, YES!

while i was posting the above response i was remembering SBU's own race bikes we have all seen built on this very forum.

and then I remembered; ohh, wait.. didnt they have an actual SUPERBIKE?!! sure enough.. Fvcking Unicorn, alive and well in the wild :fork

here's the FOR SALE thread!!, MOTEC (M1 SBK SPEC) ECU, factory spec and fully refreshed suspension included and all :fingr:

Yamaha YZF-R1 Machine - This bike was a factory Yamaha YZF-R1 Superbike that competed in the British Superbike Series. The bike was ridden by former factory MotoGP rider John Hopkins. It was purchased fully refreshed for the 2016 season directly from the team owner. Included with the sale is data from both Milwaukee Yamaha and Tommy Hill Motorsports. This is the closest thing to a current-spec World Superbike a mortal can expect to own. This bike can win races at any level.

Motorcycle is 100% fresh and needs absolutely nothing.


This bike does not include a title, nor does it have a vin number.

Yeah and I think even SBU themselves wouldn't call this a WSBK spec machine. I mean, in their own ad they state "This is the closest thing to a current-spec World Superbike a mortal can expect to own"


Ps: They said 'mortal', don't blame me!:grin2:

interesting, looks like SBU is at it again.. sure SBK builds are completely out of reach of 'mere mortals'.. :hammer: :no

fvck i hate that term now; modding, not for the faint of heart :lol

Broke his leg and made a quick recovery and was still competitive.

He is immortal.
from quick recovery involving a broken leg to 'immortal'.. uhhmm.. yeah i guess :fingr:

from 2017:

But the 38-year-old doesn’t believe that he could have kept pace with title protagonists Marc Marquez and Andrea Dovizioso in any case, owing to the Yamaha’s recurrent rear grip problems.

“For me, not a lot better because I have too many problems,” Rossi conceded when asked how much higher in the championship he would've been without his injury.

“During this season and like we spoke before Silverstone, I already said that I was not strong enough to fight for the championship.

“So, realistically speaking, even if I don't break the leg, I can't fight for the championship because I was not strong enough. I was never able to do two good races in a row.”


mortal :lol :dunno

all bikers owe him and that 2000-2008 generation of riders who risked injury to develop the inertia module...
Rossi sustained a broken leg in 2017, while riding dirt.. at his ranch..

inertia module wouldnt do shit for him in this particular case :hammer:

I've scrapped the curb feelers on my '15 (the pegs underneath footrests). I'd like to think that's around 55 degrees, but I dont really know. Front tire was std 120/70. Rear 190/50. Michelin 2CT's front and back. I am going back to the 190/55 next tire change (got a great deal on the 2CT'S ) but not scrapped them the track. It was on NC181 heading up to Mountain Crossing (the store). I am pretty sure that I have seen a couple forum members there, although they haven't introduced themselves. Hey to those guys, dont be bashful, I'm just a crazy old man! Come by and say hi!
