Title: 05 CR250 Handlebar Buzz
Post by: Nospeed on March 23, 2011, 04:13:17 AM

Whats the best way to reduce the handlebar buzz on an 05 CR250? I have seen a number of solutions but I would like to know what people have had the best luck with.

You are talking about the vibration through the bars? A thicker, softer set of grips will take the sting out of it, but I couldnt belive how much my rm250 buzzed, but now ive got used to it i dont notice it, just get some more seat time and youll stop noticing it  :D

rubber bar mounts, flex bar, 1 1/8th bars, thicker softer grips

Spray foam insulation, silicone caulking, length of rubber hose, all work pretty well as cheap solutions to dampen vibrations when "installed" inside your bars.

Just in case I would check all your motor mount bolts/head steady bracket to make sure nothing is cracked or loose.

One thing to check and replace are the springs for the exhaust.  I thought mine were fine...  but during a rebuild I replaced them as they're cheap...  HUGE difference...  Changing the springs cut the vibs down considerably.

I got an 05 CR and dont really notice any vibration, but i have TAG fat bars and some reasonably thick Ariette grips.

I have an 04 and my son has a 2006. The bars are rubber mounted stock. The rubber mounts get hard and brittle every few years, Change them out with OEM Honda parts, and don't over torque them.

The RG3 4 rubber mount t. clamp is awesome, I,ve been using them since 01. My cr125,s have higher and farther forward custom clamp, only 230.00 for it last year, I bartered a little bit. The clamp should help ya, but there,s rubber snakes to stick inside your bars too. I  like honda,s stock grips, there good and sticky.
