Honda TRX250R

From Wikipedia, the free encyclopedia

The Honda TRX250R is a sport ATV manufactured by Honda between 1986 and 1989. It combined a lightweight frame and good handling, with a powerful liquid cooled two-stroke engine and six speed close ratio transmission. Although only manufactured four years, the "250R", as it was known, was long a primary choice for ATV racers, dominating entries in most forms of ATV competition until the resurgence of factory involvement and the rise of advanced four-stroke sport ATV's beginning in 2003.

[edit] Engine

The design recognizable as the TRX250R's engine first appeared on Honda's three-wheel ATC250R in 1985. The engines of the 1986 ATC250R and TRX250R are identical, but the design was evolved slightly in 1987. Smaller changes were made in 1988 and 1989. All of the liquid cooled ATC and TRX engines are interchangeable between the different model frames, however some internal parts between the motors are not. Also pilot cylinders will interchange with case modifications, as well as dirt bike motors with front motor mount modifications, there are performance manufactures out there that will aid in highly modifing the TRX250R to your liking, like FTZ, ESR, CTracing, etc.................. do your homework RUSTYATV before sounding like a D.A., any body who has ever had in background with this quad should know that the sky is the limit when modifing it. being the owner of, oh i don't know 6,7+ Rs from 1981 up, currently adding another three 1986 TRX250Rs, i think that this would give a guy a little bit of say on want can a can't be done.
