The Honda CRF150RB Expert was a racing dirtbike that debuted in 2007 alongside the standard model and competed 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.
In 2009, the Japanese motorcycle manufacturer launched the Honda CRF150RB Expert, a motocross machine designed for taller riders, with a taller seat, larger wheels and more ground clearance, a larger wheelbase, larger tires, a longer swingarm, and a larger rear sprocket for better acceleration.
The 2009 CRF150RB Expert packed the same updates received by the standard model, which included new graphics and a redesigned muffler with improved exhaust flow. Besides that, the bike remained largely unchanged compared to its predecessors.
In the power department, the 2009 Honda CRF150RB Expert packed a powerful Unicam four-valve engine that delivered impressive power at a wide rpm range, and it only weighed 20 kg (44 lbs).
The model was built on a lightweight aluminum frame that housed 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 the braking performance, the bike packed a single 220 mm disc with a hydraulic caliper on the front wheel and a 190 mm disc with a hydraulic caliper on the rear wheel for optimum stopping power.
