hard turning slippage!

#1 Unread post by driftage »

Okay, im kinda new to this site but here it goes.

The story:
Pulling on to the I15 pretty agressive lean,smooth throttle, but the rear end starts slipping ALOT. Im thinking its my tires, i want to lean in more, but i get this feeling it will just drop out under me. I end up taking the turn a bit WIDE, and almost go into the next lane.

I didnt go over a slippery surface, i pull onto that road everyday, but that day i tried to push it just a bit harder.
Not sure what it is, or was? It was pretty cold and moist out, and the tires are about 600 miles old only.

Any Ideas?

I'd say that what you encountered was just enough moisture on the road to cause your tires to slip out. Cold damp days will do it every time. You lucked out in that you noticed what was happening and didn't do anything sudden.

Pay attention to that 'spidey sense' like you had, that leaning more would be disaster. Chalk it up to lesson learned.

How far had you ridden before you hit this turn, tyres do need to get to an operating temprature to make them sticky. Also if your tyres are too soft they will get squirmy. Whenever I go out, every time without fail in my first km I will test my brakes and work my bike left to right to warm the edges of the tyres. It's an old trick but it works.

hmm thanks for the reply guys.
well i did JUST pull out of work, it was about 40 degrees outside so the tires were most likely still cold.

what are some ways to warm em up?
other than weaving from side to side, i dont want people to think im drunk!

oh and one last thing.
Im pretty new to riding, bout a year old. I ride almost everday--LOOOOVE IT!!! took the msf course!! Im on a 500 right now and i still havent seen what that bike can really do.what i would really like to do is take on a track so that i can really play with it. Not really in the mood for speeding ticketts thats why. ANy ideas????

another thing about sliding out on cold tires. iknow it wasnt cold enough the day you were riding, but if you ride when it is below freezing you will notice it also because even if it doesnt rain the roads will still get dewed so if you are on a road not often traveled then be extra careful in the morning as the dew has been run off yet.

Cold Tires + Cold damp road = much less traction

BTW good job on keeping it upright, a lot of riders might have lowided given that situation.

Should you get in a situation in the future where you dont have the option of running wide what you can do is immediately get the bike upright and straight and grab some brakes (only after the bike is upright). Basically the same procedure that they teach in the MSF course for doing an emergency stop during a turn.

If you can get track time and an experianced track guy to help you it will benefit you hugely. Not from a point of riding on the street like you do on the track but from knowing where your limits are.

Double check your tirre pressures. When the pressure is below normal, it'll make the bike feel squirrelly in a lean. About half the time somebody asks me for help with a handling problem in a lean, it turns out to be tire pressure.

thanks for all the input.
ill check the pressures, and do a bit more warming up before i decide to push my tires. especially since its winter.
you guys probably saved me from a potentially nasty dump; thanks again.


see you on the road!

I had the same problem once in a while this summer, especially after working the night shift.

I only let it happen twice, the first time I thought it might be the suspension, but didn't make any changes. The secont time I realized that going from a perfectly straight road into a tight turn after only 2 minutes or so of riding was a bad idea. I've slowed up there ever since.
Of course I'm generalizing from a single example here, but everyone does that. At least I do.
