Honda CRF150RB [2008-2011] Review: A Pint-Sized Motocross Legend That Still Thrills

Introduction

The Honda CRF150RB isn’t just a motorcycle—it’s a rite of passage for aspiring motocross riders. Produced between 2008 and 2011, this 150cc four-stroke mini beast bridges the gap between entry-level play bikes and full-sized competition machines. Designed to dominate 85cc two-stroke rivals while offering Honda’s legendary reliability, the CRF150RB remains a sought-after weapon for young racers and lightweight adults. After spending days thrashing a well-maintained 2010 model through rocky trails and motocross tracks, it’s clear why this generation still commands respect in the used bike market.

Design & Ergonomics: Big Bike Attitude in a Compact Package

At first glance, the CRF150RB looks like a scaled-down CRF250R—and that’s intentional. The aggressive Red Bull-inspired Honda livery, twin-spar aluminum frame, and inverted forks scream “serious race machine.” With a seat height of 866 mm (34.1 inches), it’s surprisingly approachable for riders transitioning from 85cc bikes, yet tall enough to prevent that cramped “kid’s bike” feeling.

The 77-84 kg (170-185 lbs) curb weight (varies by year) makes it flickable mid-air yet stable at speed. Narrow bodywork lets you grip the bike with your knees effortlessly—a godsend when tackling whoops. The one-piece seat-to-tank transition feels organic when shifting weight forward under braking. My only gripe? The foam could be softer for marathon trail sessions, but that’s an easy fix with aftermarket options from MOTOPARTS.store.

Engine Performance: Four-Stroke Fury Meets Tunable Charm

The 149.8cc liquid-cooled four-stroke is where the CRF150RB truly shines. Pumping out 23 PS (17 kW), it delivers linear power that’s less intimidating than two-strokes but still thrilling. The Keihin carburetor (set at 2.25 turns out on the air screw) offers crisp throttle response once warmed up.

• Low-End: Torque builds from 6,000 RPM—perfect for technical climbs
• Mid-Range: 8,000-10,000 RPM is the sweet spot for clearing tabletops
• Top-End: Screams to its 13,500 RPM limiter like a deranged hornet

Compared to smokey two-strokes, the engine’s broad powerband lets you short-shift in mud or rev out on hardpack. During my test ride, the bike pulled strongly up steep inclines without stalling, though serious racers might want a 53-tooth rear sprocket (stock gearing: 15/53) for tighter tracks.

Handling & Suspension: Precision Meets Playfulness

The 37mm Showa USD forks (342ml SAE 5W oil per leg) and Pro-Link rear shock create a plush yet controlled ride. Over square-edged bumps, the front end stays planted without deflecting—a testament to the inverted fork’s rigidity. I bottomed out only on full-throttle G-outs, which could be remedied with thicker oil or preload adjustments.

At speed, the CRF150RB feels telepathic. Flicking it through S-curves requires minimal input, while the IRC tires (1.0 bar/14.5 psi recommended) provide surprising grip on loose terrain. Braking is confident thanks to the front hydraulic disc, though upgrading to sintered pads (available at MOTOPARTS.store) would enhance bite during aggressive downhill runs.

Competition: How It Stacks Up Against the Contenders

1. Kawasaki KX100

The KX100’s two-stroke engine delivers more peak power (28 HP) but requires constant clutch work in technical sections. While lighter at 74 kg (163 lbs), it lacks the Honda’s low-end torque and has a dated conventional fork.

2. Yamaha YZ125

A full-sized two-stroke with brutal acceleration, the YZ125 demands more skill to ride fast. At 89 kg (196 lbs), it’s heavier and taller (965mm seat height), making it less ideal for smaller riders.

3. KTM 150 SX

The Austrian two-stroke offers cutting-edge components like WP suspension and a hydraulic clutch. However, maintenance costs are higher, and its power delivery is less predictable in slick conditions.

Verdict: The CRF150RB strikes the best balance for riders wanting four-stroke reliability with race-ready performance. It’s the only bike in its class that works equally well as a learner tool and competitive race machine.

Maintenance: Keeping Your CRF150RB in Fighting Shape

Valve Adjustments

• Intake: 0.13-0.19 mm (0.005-0.0075 in)
• Exhaust: 0.23-0.29 mm (0.009-0.0114 in)
  Check every 15-20 hours—tight valves are the #1 cause of hard starting. Keep a feeler gauge kit from MOTOPARTS.store in your toolbox.

Oil & Fluids

• Engine Oil (with filter): 570ml SAE 10W-30 (API SG+)
• Coolant: 800ml ethylene glycol
• Brake Fluid: DOT 4
  Change oil every 10 riding hours and coolant annually. Never mix brake fluid types!

Drivetrain Care

The 420 chain (126 links) needs regular cleaning and adjustment. Pair MOTOPARTS.store’s chain brush and lube kit with a 15/53 sprocket combo for optimal longevity.

Winterization Tips

• Stabilize fuel
• Remove/charge battery
• Coat metal parts with anti-corrosion spray
