  1. Introduction

 

The CRF150RB is Honda's smallest motocrosser, a serious competition machine, and the perfect gateway to the championship-winning full-sized CRF250R and CRF450R.  It features a four-stroke Unicam engine - unique in the mini MX world - that delivers smooth, ample power and torque across the rev range. Showa suspension components comprise a 37mm inverted fork and a Pro-Link rear-swing arm with a single Showa shock matched to a lightweight steel frame. For 22YM it receives a graphic update to bring it in line with its larger CRF250R and CRF450R siblings

 

 

2 Key Features

 

 

2.1 Chassis

 

  • Lightweight, high tensile steel frame
  • 37mm leading-axle inverted Showa cartridge forks
  • Pro-link swingarm
  • Large 19in front and 16in rear wheels
  • Single 220mm front and 190mm rear brake discs
  • CRF450R style bodywork featuring a low 866mm seat height
  • New all red paint scheme for 2022

The CRF150RB features a lightweight, high-tensile steel frame with large-diameter frame tubing and cross-member for excellent turning performance and straight-line tracking.

For optimum compression and rebound control, the CRF150RB uses 37mm leading-axle inverted Showa cartridge forks with friction-reducing technology, paired with a Pro-link swingarm.

Both front and rear suspension also feature settings unique to the CRF150RB to further deliver ideal bump absorption characteristics in even the toughest of track conditions.

Lightweight single discs, 220mm front and 190mm rear, are grabbed by high performance pads offering powerful and precise braking into the turns. An HRC works-type rear-brake system integrates the rear master cylinder and fluid reservoir, eliminating the separate rear master-cylinder reservoir and hose.

 

Like every member of the Honda off-road CRF family, the CRF150RB wears its heritage with pride. The 4.2L upr

A twin-sump lubrication system reduces the amount of circulating oil and employs a smaller oil pump that separates the oil supply for the crankshaft, piston and valve train from the clutch and transmission. This ensures a regular supply of cool oil to the clutch and eliminates any potential clutch and transmission material contamination.

The CRF150RB features a smooth-shifting, close ratio five speed transmission that is matched perfectly to the broad powerband for strong. engaging performance in any gear.
