1981 Honda RS250T




Same as RS200T models RS250T was made following same philosophy. The bike was designed and manufactured for competition use only.
The bike did not conform to federal motor vehicle safety standards and operation on public streets, roads or highways is ilegal.

It appears that RS250T production was lower than TL and RS 200. In fact first development was made late on 1981 and the production was done by the renamed RSC, the new HRC Honda Racing Corporation.

The RS250T was the excellence of the RS's range. Very nice and competitive bike, based on the same RS200T chassis but modifying a little bit some parts to introduce the powerful 15Hp 249,8cc HRC engine. Like the RS200T rear wheel axle was perforated on all his extension, RS250T had also the front wheel one perforated.


The bike has no lights and any electrical installation. The front upper forks were covered by a nice aluminum plate.



Front forks were improved from the RS200T adding a connection link between both fork tubes in order to balance the inner air pressure.


To reduce the fuel tank width and allow to assemble the high performance Keihin 22, the RS250T had a really special shape fuel tank.



Original RS250T fuel tank color was Honda Red Accent painted. This nice unit (from Spain) was metallic silver/Honda Red Accent mixed painted on a personal choice of color.


The final appearance of the bike is really a professional prototype!!



The RS250T silencer, HRC logo engraved and two exhaust outlet.


The RS205T silencer had two exhaust outlets and the de new HRC engraved logo. The TL200RII and RS200T models had only one and the RSC engraved logo.

The RSC engraved logo, one exhaust outlet form RS200T

A very nice aluminum silencer replica for RS200T, RS220T, Honda SEELEY and TL200RII.


An other difference between RS200T and RS250T is the color of the wheels, the RS250T had yellow anodized finish, the engine had also different color painting, the RS250T was black color instead Metallic Silver.

In some RS250T units we can see special air expansion chamber on exhaust. Not all the units had this feature and not all the expansion chambers were made on the same way or shape, this is something that was hand made specially for every unit.
