The Honda TRX250R is one of the most iconic two-stroke quads ever produced. Even many years after production ended, it remains a popular choice for racing and high-performance builds.
Its history is closely connected with the Honda ATC250R, the legendary three-wheeler developed for racing. In 1985, the ATC250R received a liquid-cooled 246cc two-stroke engine and a 6-speed transmission.
Honda later used this successful concept as the basis for the four-wheeled TRX250R, also known as the FourTrax 250R. Produced from 1986 to 1989, it became one of the most successful racing quads of its era.
To help keep these legendary machines running, MotoGears has developed a newly manufactured 6-speed replacement gear set for the Honda TRX250R.
The gear set was developed in cooperation with Duncan Racing in the USA. Duncan Racing supplied the original parts and provided valuable technical consultation throughout the project.
The new gears are manufactured by MotoGears in the Czech Republic, with a focus on strength, precision and reliable shifting.
The currently available set includes all transmission gears. Shafts and shift forks are planned for production later. Individual gears are also available separately.
MotoGears gears are designed to be compatible with OEM transmission components and can be used as direct replacements.
MotoGears gear sets use the 1987–1989 Honda TRX250R transmission ratios.
When installing the gears in a 1986 Honda TRX250R or a 1985–1986 Honda ATC250R, both 5th gears (M/S and C/S) and both 6th gears (M/S and C/S) must be replaced and installed together as a complete set of four gears.
For customers in Europe and other countries, the gears are available directly through the MotoGears e-shop.
For customers in the United States, the complete gear set and individual gears are available through our official partner:
Duncan Racing International
This provides US customers with faster domestic shipping, local technical support and no additional import duties.
