Tail wag on hard braking

Hello,

I have a question about this bike feeling like the back and is wagging a little under hard braking. My previous, and first, bike was a 700lb cruiser and I never experienced this. Could this be happening because of the slick pavement out here in Las Vegas or is this a trait of a more sport oriented bike. The few times I have noticed this the rear tire was not locked up, per observation of the other riders I was with. The front of the bike feels planted but it is the rear tire that makes me ask this question.

Thanks

too much rear brake. I've done that in a hard braking situation (oh s*&t, the light's red) Don't be afraid of the front. You have a lot more stopping power there. Practice your emergency braking in a parking lot.

I'd try turning up the front preload. That will keep the front from diving too much on a hard stop, therefore keeping the bike more level and more weight on the rear wheel.

No matter what you do these bikes have a tendency to get light in the rear on a hard brake. I've locked my rear wheel up a couple times on quick stops(painted lines suck). The first time it happened I didn't realize it until I let off the brakes and rear end kicked over a few inches as the bike staightened out. Scared the crap out of me. The skidding tire made no noise at all:shock: .

Thanks for the replies. I am not afraid of the front brake and maybe a front preload adjust is what I need.

Thanks again

As long as the tail doesn't wag the dog, you're alright.

The rear tire can be slipping and therefore "wagging" without being locked. Since there is little weight on the rear during hard braking there is little holding it in place. If you watch motorcycle races you can see them slide the rear tire into corners without locking the rear tire. The same idea is what is happening.

spongebob,

You get a gold star for the day! I took all of the advice here, practicing stops, using more front brake and things still did not feel that great. Then I cranked the preload up to one from the hardest and the bike rides so much better. Even with a little more of a active ride it is a definite improvement. Without all of the dive in the front end, while braking, I really get a lot of good feedback from the brakes and this gives me a lot more confidence to really grab a handfull. It was the feedback that was missing with the front end being too soft. I could just not get a fell for how much brake I was applying.

Thanks!

Good deal. Now you just have to fine tune it so you still have good brake feel without the front end slamming over bumps.

Changing the preload will only change the ride height. It won't make the suspension harsher.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.
Nicknames I use to lessen typing, Vee = 2002-2012 DL1000s. Vee2=2014-2016 DL1000s. Wee = 2004-2011 DL650s. Glee = 2012-2016 DL650s
