2010 Kawasaki KX450F Fast-Aid Project Bike Photo Gallery

MotoUSA pro-level test rider Matt Armstrong shares how he sets up his personal ’10 Kawasaki KX450F.

See photos and images of our test rider’s 2010 Kawasaki KX450F Fast-Aid Project Bike in the 2010 Kawasaki KX450F Fast-Aid Project Bike review.

Armstrong’s KX450F sports special Dirt Digits backgrounds for Mammoth Motocross races.

Factory Connection fitted a softer shock spring and modified the way the oil flows inside the shock based on Matt’s speed and riding style.

Test rider, Matt Armstrong is faster and lighter than what the fork is set-up for stock so Factory Connection modified the way the oil flows inside the shock based on Matt’s speed and riding style.

The stock 0.48 kg/mm fork springs were retained but the damping settings were changed to give it better initial response over small bumps and better damping progression when loaded.

Fresh Dunlop Geomax MX51 intermediate terrain tires replaced the stock Bridgestone’s.

A shorter McGrath-bend Renthal Twinwall handlebar was fitted to increase rider comfort.

Armstrong complained that initial fork damping was too stiff when stock. Factory Connection made it much more plush and responsive feeling.

With a few simple modifications Armstrong’s KX450F was much easier and fun to ride.

Rather than re-pack the stock muffler we replaced the entire exhaust with an affordable Yoshimura RS-2 Comp Series Full Exhaust System (available at Motorcycle-Superstore.com).

The Yoshimura pipe improved mid-to-top engine performance as well as gave the engine more over-rev.

An eye catching gold-plated DID 520 ERT2 Chain (available at Motorcycle-Superstore.com) replaced the stretched out stocker.

The Renthal Twinwall McGrath-bend handlebar (with soft Renthal waffle-style hand grips) sits inside a Pro Circuit handlebar clamp designed for better handlebar rigidity in case of a crash or tip over.

Without question, Armstrong’s ’10 Kawasaki KX450F is one of the sharpest looking dirt bikes we’ve seen this side of a factory racebike.

The Hard Terrain fuel/ignition map allowed the rear tire to hook up better yet also reduced the bike’s propensity to wheelie out of corners.

A one-tooth larger (51) Renthal 520 Twinring Heavy-Duty Rear Sprocket is both lightweight and durable with an aluminum center and steel teeth for better durability.

Armstrong sports Shift’s new 2011 Strike Hyde off-road pants, jersey and gloves.
