New front brake caliper is a Pretech P824. It bolts directly on. It is a 6 piston model that only required new brake lines. Bleeding the front brakes was a pain. Mono shock is from the German company Wilbers. Model 640. Spring preload is adjustable with a spanner wrench, rebound is adjustable as well. Both can be adjusted on the bike with the seat in place. The only USA distributer is Beemershop.com. British Customs drag pipes. I DO have the cat in place. I can say that below 2500 rpm they are about as loud as the original pipes. Above 3000 rpm they really come alive! I also installed a brass gas cap from A&J Cycles. The last thing was to drill out a little larger the pin for the high bars. This gives more than enough adjustment for me without compromising safety. Very happy with all these additions. I'll report back when I have a few more miles on the front brakes.

Looks good! Digging the brass contrasts.

I really like to the look of the BC drag pipes.

Function and form

Nice mods, update us after awhile on the mono shock.

Also, what brake line upgrade did you have to do for the Pretech?

Anyone know of a U.S. distributor for this caliper? I can't find anything on it in Google.

The front brake line is actually 2 different lines. You only need to change the lower because of the adapter angle to the caliper itself. I chose spiegler lines.

I ordered the caliper from the pretech UK website. It
was 335 British pounds including shipping.

Hi Guys - I know this is an old thread, but any updates on how you got on with the Pretech caliper? I still prefer the look of this to the Bembo solution, but did hear stories of it being all a bit wooden. Does anyone know the hydraulic ratio it gives?

Cheers, Steve.

I seem to remember stock at 7.4 pretech at 9.5 Brembo at 11.8 (I have this one) 4pad Brembo at 13 really nice (I wish I had this one)

The Pretech is an improvement, but not as much feel as the Brembo's.

Looking very slick indeed.

Well done..:grin2:

Cheerio,

Thank you; very useful answers (and a good memory!)

Don’t mean to be a party pooper, but I also purchased the Wilbers 640 for my BB and the triumph dealer install it with the preload adjuster on top. After seeing your pics (nice bike!), I noticed you installed it with the preload adjuster on the bottom. I called the Wilber’s dealer to find out which is the correct why and they said preload goes on top. Could be you have reason to it that way, just thought I would pass on this info.

Well spotted!
Here is the backup to your (very valid) point:
