HONDA CRF150RB Expert (2011-2012) Specs, Performance & Photos

The Honda CRF150RB Expert was a racing dirtbike introduced in 2006 and first released in 2007 as a competitor 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 had a weight of 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.

In 2012, the Japanese motorcycle manufacturer launched the Honda CRF150RB Expert, a dirtbike that came with some improvements, such as a new cylinder head, a new piston, a new camshaft, and a new carburetor that improved power, torque, and driveability throughout the powerband.

Also, the suspension system was improved with new valves both front and rear, which enhanced suspension action, especially over smaller, faster bumps that unsettle a bike's chassis.

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.

The braking performance remained unchanged compared to the previous models, with a 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.
