Title: Burman BAU gearbox
Post by: Arnaud on November 27, 2012, 03:16:34 PM

Hi,
I'm new on this forum.
I'm French and a french bikes Terrot lover!
I'm looking for a four speed Burman gearbox, BAU type...that I can't find here in France...so, I'm looking for some help!
Does anyone know on which type of bikes I can find such a gearbox?

Thanks for your help, with excuses for my "strange" English!

Any idea what is different about the BAU to the BA - which are a fairly common type.

Hi, thanks for your answers.

The difference between BA and BAU is the fixing mode.
U means Under : the motorcycle frame goes under the gear box, which is fixed by 4 bolts...I try to find a picture.

Has someone already seen that kind of gearbox?

i have a burman box converted to foot change with a external mech made by" Veloce" , sounds french , but the box is fitted to a italian MM @1930 , you may be able to convert

Wetdog - Velocette were pioneers of footchange in the UK, and before they adopted "Velocette" for all their bikes they used the name Veloce. Connection?

Sounds like it. Probably someone's adapted the Velo external foot change mechanism or it's been made under licence.

i will dig it out , the mm is also fitted with webb forks (a very good copy) so under licence stands a chance , its the only foot change conversion fitted to a burman box ive seen , but im sure theres others

this is the bike i have but sods law shows the wronge side , i will drag mine out
