Factory Bike Friday: Jeremy Martin's YZ250F

Mechanic: Richard Sterling

Factory KYB and Enzo does the suspension for the Star Racing Yamaha team, and according to team mechanic Richard Sterling, Jeremy Martin likes his suspension to have a soft feel initially, but once it gets into the stroke he likes it a little bit stiff, although not too harsh.

Martin runs a factory triple clamp set with standard 22mm offset, although the clamps are something that Sterling said Yamaha made especially for Martin.

As far as the brakes, up front, the team uses an over-sized Braking rotor, with stock calipers and Braking hangers.

“The front rotors are 3mm in the back and 2.5mm in the front to save a little weight,” says Sterling.

The exhaust is an FMF full titanium with a carbon tip, which are also specially made for the team.

Sterling says the engine work is done in-house, however engine guy Brad Hoffman works closely with Yamaha. “Brad works his rear off in the dyno room coming up with a power package for Jeremy,” says Sterling. “Jeremy likes his power to come on hard in the bottom end and then he likes it to smooth out at the top, so he can manage it out of the corners.”

Crank Works does the cranks for the team, and GYTR supplies the clutch assemblies.

As far as controls, Jeremy’s bars are Pro Taper with the Carmichael bend. Levers are ARC, and the grips are Pro Taper “white soft.”

According to Sterling, Jeremy has him cut all the “waffles” off the grips.

The pegs are Raptor, and Sterling keeps them super sharp.

The hubs are factory Yamaha with Excel rims, with Dunlop tires mounted.

The radiators are stock, although they have been beefed up with welds in strategic places.
