Mechanic: Randy Mahoney
Nick Wey has been riding the KX450F for the past two years so he’s had plenty of time to get a few setting nailed down. Nick uses Pro Circuit for his engine and suspension work, along with a few other select aftermarket goodies to complete the package.
As far as the engine goes, Nick uses a higher compression piston, Pro Circuit cams, and does some porting on the head to boost the low end and give the bike a little more torque, which makes it smoother and easier to ride. Of course, a Pro Circuit exhaust draws the spent fuel from the cylinder.
When it comes to the suspension, Nick runs the new Showa air forks, set up and maintained by Pro Circuit. The team has also been experimenting with Pro Circuit pull rods and linkages at the rear.
“We’ve been doing a lot of testing and the air fork offers good small bump ride, it’s plush initially, and it holds up really good through the stroke, but it is a new feel for Nick over the conventional forks,” says Mahoney. “He typically likes the front end pretty stiff. Meanwhile, at the back we’ve been messing with some linkages to raise it and lower it, trying to get it to work a little better in the corners.”
Pro Circuit triple clamps hold the forks in place and Nick prefers a 22mm offset to help him get the bike to turn. “Nick always has a hard time in the middle of the turns, so we bring the front end in a little bit to help him get around the apex,” says Mahoney.
Other items include a new Pro Taper bar that has a new a locking crossbar, which you can lock in to make the bars more rigid, or unlock it to allow them to flex a little. Nick likes it in the locked position. Pro Taper chains and sprockets with 13/50 gearing everywhere except for Colorado. Nick likes the stock footpegs which have been sharpened.
Braking rotors and DID rims with Talon Hubs fill out the running gear.
Finally, Nick runs a Moto Tassinari Air4orce Boot with adjustable stacks (short stack).
