T110 Production Racer


Built for 1992 season VMCC 'Production & Clubman class and fitted with an alloy T100 engine. This was replaced by a 650cc engine for the 1993 season.

Final season was 1997 with Mallory practice and VMCC Round 1 at Mallory in March. Rounds 3 & 4 at Cadwell in May. Rounds 5 & 6 Lydden 31st May & 1st June.

Did 1999 AJS & Matchless club day at Cadwell in June and not used since. but stored in the house warm and dry.


If you clean the carbs and sump out and check the tappets it will probably fire up and run.

Was a really good bike to ride. with a very flexible engine that never used to give us any trouble and not highly tuned so would make a good road bike. we will be sad to see it go. but its time it got a new home and someone to use it.

The bike is located in Barnsley. South Yorkshire and would need collecting. cash on collection please.
