Hello again,

The DB1 looks a bit better now its been cleaned up a bit but the callipers will need an overhaul. Do the standard two piston Brembo seal kits fit the Gold Series callipers? Or, if not, where can I buy some seals, if possible?

Cheers, Mike J.

Hhmm touchy subject for some folk on the Forum, Brembo decided a while ago that if suppliers wouldn't sign up to an indemnity clause over seals etc that they wouldn't be allowed to sell them. There is a Brembo web site and you can try emailing them, personally I've been waiting 2 years and counting for a response. Some folk have ended up buying new calipers as a result, and some "cynics" may sat this is the reason they don't sell seal kits. KTM though dd sign up and KTm suppliers and on-line, will sell caliper seal and piston kits as they use Brembo gear.
I'd also try Rudolf at Bimota-parts.de as I'm sure he must come across this problem as he deals solely with Brembo stuff.

Foutunately for myself I took no chances and found NOS serie d'oro calipers with pads that were cheaper than seal and piston kits alone. Pictures can help reponses GREATLY, then the knowledge of other folk can come to the fore, not all so fortunate to have a DB1

Hello 2bims,

thanks for the info. Motobins were certainly doing Brembo kits until recently, so I'll check the piston sizes and try them. Just to rub it in, it appears the bike is a DB1S! (The 'S' on the fairing and 40mm carbs were the giveaway)

Cheers, Mike J.

How long have you had the DB1 Mike?

Well, Pompey, I've had the bike for about five years but its was pushed up against the back of the garage with the front of the fairing out of view, so I didn't spot it until after I'd checked the carbs. (Funnily enough, 2bims, the rear wheel was like the works racer so who knows!).

The brakes seem to have 32mm pistons, which seems a bit small, but the R80R BMW seems to have the same size pistons, so I'm investigating...

Cheers

Hello 2bims,

checking the (high) frame number in Georgio Sarti's book comfirms that it's an SR, although it's been fitted with an earlier engine! It probably explains the rear wheel.

P.P.S. I've just taken out insurance on the cat!

Heres a link for you for seals. The same company have advertised on here for GP500 screens for most Bimotas, including DB1's and some folk have recommended them, lots of goodies on here, click on the link and then you'll see that they not only offer the calipers new at a good price (although you'd have to spray them gold if you wanted originality) they also have seal kits for them too, happy shopping

Thanks 2bims, I'll be investigating!- It's good of you to take the time. I'm stripping the DB down at the moment and it seems to get smaller and smaller-at the moment it looks about the size of a 125. It wouldn't turn over intially, but the fault was the !"£$%^!! kill button. I had the same problem 25 years ago on a Pantah, so will probably fit a replacement Japanese R/H throttle switch assembly. The kill button reads perfectly when tested and then plays up when back in the bike

No Worries, I spend time scanning for other bits and was there looking for a DB4 screen to replace the dubble bubble, and if ever I find something on the way for others that I know, I pass it on, so no problem. Had kill switch problems myself, corrosion inside the cabling would be the issue, I bought a replacement kill switch as mine would choose to work, or not, or not when it should, or would when it shouldn't. Only after the replacement arrived after some more miles did the old switch then decide it was fine after all and didn't need replacing. I now never ever touch it, its in the Run Position and there it shall stay, until MOT time

Hello 2bims,

could you please check the piston sizes on your gold series brakes, when convenient, as mine seem to be 32mm, which I would have thought was smaller than the standard P08s!

Cheers, Mike J.
