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.
