Inner tubes & Outer-tubes


If, due to falling rocks, accident or simply wearout, a sliding-pipe or standpipe is damaged, the repair or exchange will surely cost a lot of money. The reason for the high invoice is that motorcycle manufacturers normally deliver USD sliding-tubes only with screwed on axle drop-outs. But also with RSU forks one might save up to 50% expenses!

The high-class sliding-pipe by Promoto with its sophisticated chromium surface offers best response characteristics and a very long lifespan. For an additional charge we deliver Promoto tubes with titan-nitride or even carbon coating.
