3-speed gearbox
Gearbox
Bentec 3-speed transmission.
This is actually not a Bentec ”product”, it’s more a combination of the SS Classic 2-speed gearbox! We have made a couple of these builds for some Top Gas Harleys and new-age Funnybikes out there. There are also a few built by customers of their own design, by using inserts of the 2-speed SS. We can supply all parts needed or put the complete unit together. One of the most successful 3-speed bikes is Storm, the UK-based methanol funnybike of Mike Hand, with a PB of 6,56s @211mph.
