Transalp Brakes

Stock Rotor

The stock Honda Transalp rotor is 276mm in diameter.

Hawk Rotors

The Honda Hawk uses a 316mm rotor. (this page has excellent Hawk information)

Spacer

This thread (advrider.com) mentions a guy making a spacer so you can use a stock Hawk rotor (316mm) on the TA (276mm stock).

Anyway- potential very good news- I asked the guy who built a brake 
kit for Honda Hawks (a 6 piston caliper and GSXr rotor- works great- 
I have one on my Hawk) to look at a potential TA solution. He designed 
and built a bracket that relocates the stock TA caliper so that you 
can use a stock Hawk rotor which is larger (and I think a little 
thicker) than the stock TA rotor. Combined with steel braided lines 
and HH pads (which he thinks might not even be necessary) this should 
provide a relatively inexpensive upgrade to the TA.

I should be doing this in the next month or so and will let you all 
know how it works. Keep fingers crossed

This thread (advrider.com) mentions the Hawk rotor again.

Stainless brake line is a good investment. Speigler, and Galfer both offer
one. Maybe others. The trick brake upgrade is get a used rotor from 88-91
NT650 Hawk. Same bolt pattern but 40mm bigger diameter. Then you have to
machine an adapter to offset the caliper. I'm working on this now.

Also:

Steve (Fast By Big Boy) Lenac (bigboy11@sigmaweb.net) has (or will
shortly have) the full kits for this. I have one on mine (shown in 
the "show me" thread) and it makes a difference.
