MOUNTAIN MOTORSPORTS YZ450F: PROJECT BIKE SPOTLIGHT

On this week’s Project Bike Spotlight we take a look back at our Mountain Motorsports YZ450F motocross build from a few years ago. Thumper Theater is pack with four different custom projects for your viewing pleasure and check out the exclusive link to our Dubya USA YZ450F build at the bottom of this post!

 The Super Grip cover from Seat Concepts features a rubber grip patch to improve bike control and prevent damage. Joel and the crew at 707 Racing Suspension re-valved the forks and shock to fit our personal riding style.

Warp 9 wheelsets are completely customizable and feature a billet-aluminum hub, anodized 7000-series aluminum rim and stainless steel spokes. The STI Tech 2 MXC tire features a four-ply carcass, advanced-wear rubber compound, and a semi-wide tread pattern for dependable traction. Made of 4100-series chromoly, which is a blend of chromium and molybdenum, along with manganese and nickel, the MSR 41Hundred sprocket is all about wear resistance.

Cycra’s PowerFlow Intake radiator shrouds have a single-piece design that narrows the bike and improves overall air flow for increased performance. MSR skid plates are injection-molded polypropylene and feature full-coverage protection. Torc1 Racing Voltage footpegs are cast steel and 58mm wide with an aggressive tooth design for maximum grip.

CV4 silicone radiator hoses not only add a cool look but also improve coolant flow, which lowers operating temperatures.

Twin Air’s Power Flow kit eliminates the need for an OEM backfire screen and includes a billet-aluminum cage with a special backfire-resistant layer of foam laminated to the inside of the filter.

Barnett’s clutch baskets are CNC-machined out of billet aluminum and feature patented Second Generation stainless steel inserts to virtually eliminate grooving of the basket fingers.

Jared Hicks at Backyard Designs gave the Mountain Motorsports YZ450F that factory look we wanted with a semi-custom graphics kit to match the Seat Concepts gripper seat.  Dubach Racing Development’s stainless steel and aluminum exhaust system is designed to improve performance throughout the power curve and is spark-arrestor-friendly.
