My friend has a 450 and as everyone knows at high speeds the front end can get a little shaky u know
How can he fix that problem

 

I can run mine at 75 mph (GPS) down a road right behind my house no prob, no shakes what-so-ever. Check to see if he bent a rim or axle, sounds like something isnt tight or the front wheel bearings are bad??

BTW, i got my front fenders shaved.. that probably helps too.

 

It was reported in Dirtwheels that it was shakey at top speed but I have had mine pinned at the rev limiter in 5th many times and have found it to be stable. No complaints from me.

 

Hasnt happened to me at all, even when i found its top speed at 78 mph.

 

Any bike that gets ridden fast, should have a steering stabilizer! Is he running stock tires/rims, or something else?
