HONDA CRF150RB Expert (2006-2007) Specs, Performance & Photos

The Honda CRF150RB Expert was a racing dirtbike manufactured in 2007 alongside the CRF150R standard model. The Expert was a nifty Honda solution meant to provide taller riders with the same comfort and maneuverability as the standard model.

In 2007, the Japanese motorcycle manufacturer launched the Honda CRF150RB Expert, a motocross machine that offered a taller seat, more ground clearance, a larger wheelbase, larger tires, a longer swingarm, and a larger rear sprocket for better acceleration.

At the time of its release, the CRF150RB Expert, was sold for an extra $100 due to its modifications to suit larger riders. All the extra features added only two kg (four lbs) to the bike's overall weight and were referred to as the CRF150RB, where the R suffix came from Race and B suffix came from Big Wheel.

The bike had at its core a powerful Unicam four-valve liquid-cooled engine that delivered impressive power at a wide rpm range, and it only weighed 20 kg (44 lbs). Equipped with fully-adjustable Showa suspension, high-quality Dunlop tires, and disc brakes both front and rear, the 2007 Honda CRF150RB was one of the best mini-racing machines Honda has ever made.

For suspension, the bike featured a 37 mm fully-adjustable inverted cartridge-type fork on the front and a Pro-Link fully-adjustable Showa shock absorber on the rear for optimum suspension performance and handling.

In the braking department, the bike packed a single 220 mm disc with a hydraulic caliper on the front wheel and one 190 mm disc with a hydraulic caliper on the rear wheel for optimum stopping power.
