HONDA CRF150RB Expert (2007-2008) Specs, Performance & Photos

The Honda CRF150R standard version and the CRF150RB Expert were racing dirtbikes introduced in 2006 and first released in 2007 as competitors in the Mini Class against many 85cc two-stroke bikes. All of Honda's 2008 models were four-stroke, while the earlier ones were two-strokes.

The bike featured 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 CRF150RB was one of the best mini-racing machines Honda has ever made.

The 2008 Honda CRF150RB Expert was $100 more than the standard model and offered several new features specifically for larger riders that included a taller seat, more ground clearance, a larger wheelbase, larger tires, a longer swingarm, and a larger rear sprocket for better acceleration.

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.

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.

As for braking performance, 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.
