Lean angle thread

[carnivor32]

Cant believe we haven't had this thread up yet but let me be the first to start it up. This was recorded while street riding, not the track, stock tires, sport mode setting on suspension. actually Hit 51 degrees lean angle on that turn but of course I didn't press record on that run

Can you show us what the lean angle indicator looks like on the dash?

 

[Grayson]

No offense but I doubt it's exact and I definitely don't want to go out on the street to attempt to get my max lean angle for a picture.

I don't really look at the dash bc it's hard to see even in "night mode" it's definitely going to be hard to get a good snapshot

 

[JDBeretta]

Just post up your lap data...

 

[carnivor32]

lean angle is displayed right on the dash instead of where MPH is seen when you select race mode, the sensor is very accuate. Shot was taken with go pro but i can't post video here or at least i don't know how

This was going through some narrow twisties out in my area. Terrible conditions (frost humps in pavement, cracks, and debris - not mention I saw 2 bears and a bunch mountain sheep on the side of the road) prevent anything crazy, but you can get down enough to have a good time.

On the way back, my lap reset itself after 10 mins, I believe. I think it would have been a few deg more.

Whatever, good times.

JD that's awsome. I didn't even know you can do it that way!!!

That is cool! Too bad I dont have lean angle info...

I'm looking forward to seeing some of the track results w/street rubber vs track rubber. Just for curiosity sake. I don't think I'd be much better than 50deg on the street if I were closer to some places I used to ride at. Hopefully 55ish at the track...

Got my fingers crossed for you .

My thoughts exactly.

There is NO way that thing is accurate.

Marquez rarely hits 60deg (I believe 62 is his absolute max), and that is the very max on the MotoGP tires and while doing so he is dragging elbow, shoulder, everything.

I find it very, very, very hard to believe that people are reaching a true 50deg+ on the street, in less than perfect conditions, on street tires.

Of course I could be wrong.

 

[Chaotic]

I have no intentions of posting mine till I get to the track. And even then, it will be an afterthought.

Lean angle is the enemy. The goal is to get around the track as fast as possible, using the LEAST amount of lean angle as possible (and/or while spending the least amount of time at max lean angle).

When I saw the bikes coming with Lean Angle indicators, my first thought was "yep, that thing is going to lead to a lot of squidly crashes".

Totally agree with what you're saying, but how can an IMU that is used to dictate everything from wheelie control to suspension dampening not be accurate? We absolutely have the technology to be about as precise as you can get with bank angle sensors in aircraft and accelerometers in tons of things.

I'm going to research how the IMU works and go from there with my opinion on accuracy, as I'm conflicted right now.

Just to be clear, there are only a few important things that I care about when I ride on the street or track... 1. That I get to go home to my family with my bike and myself in one piece and get to do it again tomorrow/another day. 2. That I had a good time. 3. That I may have gotten just a tiny bit better (safer/faster/whatever) than I was before. Lean angle achievement falls into the 3,483rd spot of .... I care about.

You mean riding crossed up to make sure I have no chicken strips isn't how to become a better rider? Say it isn't so!

a street superbike, with DOT-legal street rubber, should max out at about 50 degrees. With slicks and a WSBK suspension on a prepared track, 55 degrees. It takes a MotoGP setup to get 60 degrees, and commentators have said that Bridgestone sees their tires as capable of 63 degrees, no more.

lean angle is indeed the enemy. I'm still in the break in period so I'm not flogging the crap out of my bike, but I've seen 38 degrees while hanging off like a monkey in fast sweepers. If I sat square in my seat that probably could have been 45-ish, but while the obvious temptation is to try to go for extreme lean for inevitable bragging rights (because if it can be measured, it can be bragged and argued over on the internet ), I still like it and usually have the indicator on. It puts a number on turns I've been taking for years, and helps me gauge if I'm positioning both myself and the bike (moderate lean angle + relatively fast speed = body position is doing something right). It also helps gauge if there's more speed left on the table. My favorite sweeper is one I take at about 85-95mph, regardless of bike. On the 1299, I found I my lean angle was only about 30 degrees. I then was confident about raising the speed to 110mph and still only hit the aforementioned 38 degrees.

I would love to know my lean angle only so that I can work on reducing it.

 

[Raaseri]

I try to hang on the side of the bike as low as I can. At the racetrack I get continuous 53 degrees on both sides. My pace at the moment is very close to Rookie class SBK winning times. Which in my books is a very good performance from stock bike.

I would not go for 51 degrees on the street. I could do it with leaning into wrong side and then I think 51 degrees is doable with reasonable risk on a good road and conditions. And of course, if the curve would be very inclined, then of course extra degrees are achieved.

I am conflicted also. I mean, I know we have the technology...but I can't see somebody hitting 50+deg of lean angle on street tires, on public roads.

But again, perhaps in a situation where the road is really banked, maybe. But I don't know...that is a lot of lean angle. And if somebody did achieve that on stock tires on the street, whether they realized it or not, they were on the brink of wadding their .... up.

Dude. It is hilarious how many people STILL see chicken strips as a measure of speed. Haha

Exactly.

When used correctly, I think the LeanAngleometer D) could be a useful tool.

But as we all know, its primary purpose will be for internet .... measuring. Haha
