FS 1990 MC21 F3

StephenRC45 » Tue Sep 12, 2006 12:42 am

Due to a rather large new project I'm thinking of selling my 1990 NSR250 MC21 F3 race bike.

Bike spec is:-

HRC F3 crank cases
HRC F3 crank
HRC pistons
Barrels and power valve modified to HRC spec.
HRC front head conversion
HRC F3 gear box (close ratio)
HRC rear disk
HRC rear caliper
HRC style swinging arm
HRC F3 igntion +/- 5 deg
HRC RC valve controler
HRC servo motor
HRC ECU
HRC harness
HRC tacho and stay
HRC temp guage
HRC reeds
HRC inlet manifolds
HRC air box
HRC QA throttle
HRC silancers
HRC steering damper
HRC coils and plug caps
PWK 39's
Dog fight pipes
NSR-World clutch basket
NSR-World sprocket carrier
MC28 body work
Braided brake lines
Lightened pressure plate
Dry clutch
SP forks
SP shock
Race top yoke
New chain and sprockets
Full selection of jets
Selection of Renthal sprockets

The bike comes with 6 months Tax and MOT (day time only).

It makes a reliable 70+ bhp and will distroy the average '21 and plain beat a good one. The bike doesn't have a kick start but bumps with ease. Pistons and rings have less than 100 miles. Because of the nature of the bike it does however need very regular overhauls. Squish and ignition is set up to run Unleaded.

Remember these are not just your run of the mill RS250 parts but full HRC Formula 3 parts and are very hard to come by for the MC21. This bike is nothing less than awsome to ride and is great fun on the road or the track.

Stock MC21 with HRC jet kit, race pipes and open carbs Vs F3







This is a very serious bike, none of that namby pamby race replica stuff - THIS IS A RACEBIKE!!, so I'm open to serious offers before I put it up for sale on Ebay.
