Looked to me like he was turning in too early on just about every corner, which will always run you wide on exit. Really did it badly on the corner before the one he went off on; chucked it in over the center line, picked it up and then nearly went off. Lines were in and out a bit too; most of those corners only had one true apex, but he was getting some extras in.

Riding on the double yellow is not good form at all. I'm with you Steve, he was taking 3 or 4 bites at every corner instead of one turn-in point and doing an out-in-out within the lane with margin on both sides for shoulder debris and oncoming traffic crossing the lines. The lean angle only got somewhat serious the corner before he was "spooked", I don't think he was used to going that fast and carrying that much corner speed.

Poor guy, his ego got him when he should have just stuck to absolute rule #1 - Ride your own ride...

Glad he's ok, and hope he learns from this.

On a lighter note, is your cam strapped to a bobblehead?

I Ride: 1299 Panigale S - 2013 Kawasaki ZX14R and 2011 ZX10R (Track Bike)
Warming tires up

As far as swerving back and forth (on street riding) to warm up the tires goes...

From what I have read (and what I was told by a factory Pirelli Rep) simply swerving back and forth on a motorcycle does very little to warm up tires..
It is because the load characteristics on a single track vehicle/bike are a totally different dynamic than those on car/ racecar tires..

I guess most guys see race cars swerving back and forth to warm up the tires before a race assume it works the same way on a bike but that is a different lateral load on the tires since the cars are two track vehicles and concentrate more lateral load when changing direction quickly since the tread area is basically more of a flat surface and they have a lot more load stressing the tire ie ...cars are much heavier and don't depend on lean angle like a bike does..

The design of a motorcycle tire is different than a cars tires and since it is more rounded to facilitate cornering loads and the entire carcass design is different.. simply leaning the bike on the sidewall slightly like when you are swerving back and forth at low speeds doesn't load the tire as much until you get into heavy lean angles where the carcass of the tire deforms to the road contours. Simply swerving back and forth does little to warm the tire up.. It does look cool however and I am sure it is a psychological advantage since even the racers do it. Maybe they are just trying to scrub the brand new slicks in and get the surface glaze left from the factory molds off but that is probably not really necessary. Maybe they do it to warm themselves up and loosen up themselves?

The only real way to properly warm up tires on a bike (other than tire warmers at the track) is the acceleration and braking forces on the tire.
Even with tire warmers to get the tires hot initially they still require a lot of action to keep them warm /hot IN other words taking off fast and de accelerating fast ... That is what creates friction in the plys/belts in the sidewalls and really heats the tire to any real significant degree...
That is what heats up a tire more than anything (unless it is of course leaned over at a steep angle and trading rubber for traction) in a racing or track day situation when you can keep it consistently stressed.....
Even then.. you still see/ hear about racers that tuck the front end because the track they are on has more turns in one direction that the other and the sidewall with less corners gets cooler ..

I have personally experienced this It is not fun..

glad your friend's okay.

Ya I m with you, he should have been scolded before the wreck, for crossing.


That crap is not tolerated here. We catch someone doing that in our small group, even in the rear view mirror we take action.

Ill do it to loosen up and get in the right frame of mind, every once in while.


Has nothing to do with tire temp for me.

There it is. The truth pokes its ugly head up.


Nothing personal but those bikes suck compared to ours at higher speeds.


Guy we ride with has one and anything over 80 and the guy falls way back.

He can actually outride me on his other bikes.

When you pull up off the side of the bitumen it's a good idea to swerve left to right to clean the loose dirt (marbles) off your tread before hitting the corners where you need maximum traction. When I first began riding my front end slid sideways a few times after parking on dirt. I've done the swerve since and never had a problem.

Yep. 1. Ride your own ride, and stay on your own side. 2. Clean your tires when rolling again, especially when pulling off to the side after they are already warm. Glad the guy came out of that ok.

I ride alone, because I hate that wait, then turning back looking for my riding buddy, then finding them, everyone has their own level and threshold. Glad you didn't have to get the meat wagon there.

Agreed, he was riding way above his limits by trying to keep up.
