Over doesn't make any of the racing parts for the TRX anymore as far as I'm aware. I looked into a 6 speed a couple years back and the ones that were on auction were either horribly priced or horribly worn. 
I wanted one to close the gap between 3rd and 4th that was killing drive up the hill on our circuit.

Re: 6speed gearbox upgrade
Why anybody in their right mind would use a tdm gearbox over the trx 5 speed is beyond me. Its ratios are designed for an "adventure bike" with a ridiculesly low first for climbing trees with a big gap to second and a big gap between fifth and an overdrive top (just were you dont want a big gap). The rest of the ratios are no closer than the trx box. Its effectivelly a 5 speeder with crazy ratios because first is unusable once on the move whereas the tall first of the trx is great for tight hairpins etc. Most serious riders who have a tdm motor in a trx actually put the trx cluster in the tdm. Totally unsuited to a sports road bike and a total wank.

Re: 6speed gearbox upgrade
I beg to differ, the TDM ratios feel a lot better and linear power straight to 6th.lenny wrote:Why anybody in their right mind would use a tdm gearbox over the trx 5 speed is beyond me.

The TRX has crazy ratios where one almost stalls the acceleration and 4th to 5th almost no difference.
