What to Expect

BSA A10 engine shoe-horned into Ariel chassis, makes for a pleasant enough device, especially if the engine’s upgraded with SRM parts. Prices are more reasonable than the A10, although handling isn’t quite up to that bike’s standard as stock, but lots are running more modern suspension and brakes. Age turns the electrics pretty nasty, but again most upgraded by now
