The final model that has returned to the double-sided swing arm.
Although there is a difference in the uniaxial layout of the engine, the
appearance is similar to the ’98 -’02 type NSR250.
It seems that the F / R wheels have been outsourced by “marchesini”.
The uniaxial V-twin engine seems to be a continuous development type from the NX5 type, but it seems that the
crankcase is newly designed and the front and rear length is shortened by 15 mm.
The Works NSR250
was a two-axis V-twin engine with a crankcase reed valve in the ’98 -’02 model, so
NSR and RS were evolving into different systems.

Development of the commercial RS250R was suspended until 2002,
and development was concentrated on the works machine RS250RW, and
the supply of “A kit” to the satellite team was also stopped from 2001.
With the end of GP250, sales of RS250R ended in 2009.
