Because of the Racing heratige HT Moto make some lovely speciall parts for the Guzzi.
I guess its more for Racing really , but it really cleans up the lines for a cafe racer too !
The engine breather on a Guzzi is an Ugly and pretty useless thing. Hartmut makes a moulded box that fits in the top of the frame where the battery access would normally be (see pic) .
Its a beautifully made unit that sits on the frame rails and with a little extension of pipe work from the engine, replaces the original unit really neatly. I haven't used the bike yet but it looks like one of those parts that should be good at its job and look neat too.
