I recently switched from a YZ250 smoker to a 06YZ450F, and arm pump on my throtlle hand is killing me after 5 laps on the track!

So I am looking for suggestions to help my armpump.

1) My bars are ProTaper Windham
2) I use a Scotts Stabilizer for certain off-road riding

I am thinking about an RG3 top clamp, it is supposed to help arm pump and I like the idea of having double posts so my bars don't twist when I bite it hard.

Any other ideas?

I had the protaper rubber mount upper clamp on the 250f i sold, and i realy liked it. It definitely lowered the vibrations some, and didnt let the bars twist when i fell down.

Im not totally convinced any clamp is a bolt on fix for arm pump, though it could help a little. I think that leaning forward when you get on the gas and using your legs to hold yourself on the bike is more effective than any bolt-on mod you can do - now if i didnt get lazy riding, that would be the ticket, wouldn't it? haha

Loosen up the death grip on the bars, try to use you're legs more for gripping the bike. I don't really have that bad of a problem with mine, I use stock bars, stock triple clamp. Sure I get it, but that's after like a 30 minute moto or something it would start to come on, then I try to ride through it. I rode my buddies 1999 YZ250 and that thing is crazy vibration compared to the 450f (which I hear is the most calm bike).

I had the same problem when I made the switch to a 4 stroke. I think it happens because on a 2 stroke you are using the clutch and holding the throttle pretty steady, but on the 4 stroke you are constantly needing to change throttle position. I also think these thing pull way harder then any 2 stroke can, you have to lean forward more, and grip with your legs when you get on it otherwise it will rape your energy.
