DRD Kawasaki KX450F Off Road Project Bike Photo Gallery

Dubach Racing Development transforms a KX450F motocrosser into a competent and easy-to-ride off-road race bike.

Dubach Racing Development modifies Kawasaki's KX450F for use in motorcycle grand prix and off-road races and we test it in the DRD Kawasaki KX450F Off Road Project Bike review.

The 2.7-gallon IMS fuel tank expands standard fuel capacity by 0.8 gallons which will be valuable during extended multi-hour races.

Clever modifications by DRD enhances the KX450F’s off-road riding prowess.

The Simon Smart Body replaces the standard throttle body and helps the engine pump out a smoother, more useable spread of power. Fuel efficiency is said to be increased too.

The ProTaper footpegs are even bigger than stock and are 3-way adjustable in terms of height.

Despite the added componentry the DRD-modified KX450F didn’t feel that much heavier than a stock bike.

An ARC clutch perch attaches to a ProTaper Evo-style handlebar (Carmichael bend) with hand-friendly ODI half-waffle grips.

Despite the internal configuration of the engine being unchanged, the powerband feels much smoother and more friendly than stock.

Metric bolts on DRD’s mufflers allow it to be serviced at home without the need for a rivet tool.

Although it’s a bit heavier than stock the KX450F can still be maneuvered with ease in the air.

An QTM front brake kit with AP Racing brake pads makes it easier to slow down fast when landing into a tight, slow-speed corner.

We were surprised at just how agile the KX450F was in slow speed corners.

The ProTaper Carmichael bend handlebar will be welcome by shorter-to-average sized riders.

The smoother powerband makes the KX450F less fatiguing to ride.

Factory Connection re-valved and re-sprung the suspension for use in off-road and grand prix style races.

The smoother bottom-end power helps the rear tire hook up in turns.

The Factory Connection suspension delivers a extremely plush ride that will help conserve the rider’s energy during a off-road race.
