PRO­POSAL FOR A NEW SCOOTER RAC­ING CLASS

Scootering - - Kickstart -

Scooter­ing was con­tacted re­cently by Andy Fran­cis of Franspeed with re­gards to a pro­posal of a new race class for 2016. Andy has been work­ing on sug­gested Lam­bretta spec­i­fi­ca­tions while Nor­rie Kerr of VE UK those for Vespa.

Scooter­ing un­der­stands th­ese pro­pos­als are still to be put to­wards and ac­cepted by the BSSO and mem­bers which will no doubt be dis­cussed at their AGM in Fe­bru­ary 2016.

Andy Fran­cis writes: “The aim of this new class is to pro­mote scooter rac­ing, to keep it af­ford­able, safe and com­pet­i­tive, us­ing read­ily avail­able stan­dard parts and off-the-shelf tuned road parts. This will keep the class com­pet­i­tive and the rac­ing close with the onus be­ing on the rider’s abil­ity.”

Plans

Th­ese are out­line plans which have ap­par­ently been sub­mit­ted as a start­ing point. Andy Fran­cis: “We at Franspeed are happy to sup­ply the ex­haust at cost price. We will con­trib­ute £250 to­wards a prize fund, along with ex­hausts and tail cans. We will also be offering a 30% dis­count for parts used specif­i­cally for this race class. Rayspeed has agreed to sup­ply parts to be used for this class with sub­stan­tial dis­counts. Vespa parts will be avail­able from VE (UK) at spe­cial prices, un­der the same con­di­tions as Lam­bretta parts (to riders with 2016 ACU li­cence, cur­rent BSSO mem­ber­ship and have a 2016 com­pe­ti­tion num­ber). Oil and tyres will also be dis­counted. This is not an ex­clu­sive club. Deal­ers or scooter or­gan­i­sa­tions are wel­come to come on board with spon­sor­ship and pro­mote any part which can be used to en­hance the safety and per­for­mance of this class.”
