B-Race Retro

From Plymouth, this is an SX200, sporting an Indian 200cc cast barrel off the shelf, a 24mm Delortto carb and a B-Race RETRO pipe. The pipe transformed the engine from using a Clubman exhaust, a strangled 11.1hp, to an impressive 15.8hp with the RETRO. As can be seen on the dyno printout it has a wide spread of power, and is still delivering over 14hp at 70mph. If you take the state of tune the engine (doesn't) have, this is a very respectable return in performance.
Low cost performance! And looks too!
Finished in Satin Black or, bare metal for chroming.
Available in Black, Bare metal

B-Race Retro Expansion Chamber
Fitted to Jim Wischusens GT250, (as seen in August 2005 Scootering magazine, before fitting the Retro) using AF's 250 Cylinder kit. "This is out of the four exhausts I've tried on this engine set up by far the best expansion for the AF 250 Engine must count this as THE exhaust to compliment it. Power is up and a good smooth pull from low down. With the other pipes the revs were to high or not producing the power low down so had to run a lower overall gear ratio, now I'm going back to the SX200 gearbox. Currently achieving over 22HP @ 75mph".
Jim's words, and praise indeed. He is now running a half / short footboard and full panels.
The "RETRO" pipe utilises the mechanical muffler system as used in all my designs.
This gives a unique sound, is quieter than the usual absorption mufflers used on scooter expansions, and doesn't
need packing / repacking.
Finished in Satin Black, bare metal for chroming or Chrome by order.
