Hi All,
I've just bought an FJ1200 powered bike, so i've joined to gain some knowledge on these great engines.
My bike is a Bimota YB5, 1988 model with 9,200 original kilometers. Unfortunately i have had a little electrical problem where the main loom has been shorting to the frame, so i'm now trying to formalise a plan on how best to proceed.
Here are a few pics...
ouch dude those wires look ugly......but I never knew there was a bimota with a FJ12 engine in it....cool!
That is a rare bird you have there. Not that many made with the FJ engine. Looks to be in really great shape, except for the wiring. Good luck in getting her back up running. Big R
Welcome to the forum :hi:
It is nice that you want to ride the beautiful piece of art. Most YB5 owners are collectors and they are stored away for safe keeping.
Is this the YB5 that was for sale in New Zealand awhile back??
Send me a PM about your electrical problem. I am an electrician by trade.

Wow.....lucky find!

Thanks big r,
a total of 208 were made, 12 delivered as kits and 7 in red/silver, so that brings it down to 189 units produced almost 30 years ago, no idea of how many are left.

Thanks Fred,
Not a NZ bike, i bought it from its second owner down near Eden in NSW, he had owned it for about 10 years and traveled 2,000 k's on it, he bought it from the original owner in Sydney who had ridden it 7,000 k's in 20 years!
It is in fantastic condition.... well except for the loom... i'll send you a PM later thanks.

Thanks jscdunn,
as soon as i saw it i swooped on it, not many steel framed Bimotas around.
Steve, Around a year ago there was a YB5 on eBay that had also had a similar electrics shorted out problem, but it had burned pretty seriously..... must be a common problem.
Nice find!

Typical Italian electrics.....growing up my old man had several Lancia cars....amazing cars!.....when the electrics worked :dash2:
Do you have a service manual for it?
Nice rare find indeed!

Hi Zwartie,
i have seen T-rex's YB5, hopefully i'll be taking my Bimotas to Easter Creek Raceway in March for this event https://www.internationalfestivalofspeed.com/ (https://www.internationalfestivalofspeed.com/) There is going to be a large Bimota gathering and the T-Rex YB will be there...
Could you adapt a FJ wiring harness? (popcorn)
There was a story in "Practical Sportsbike" recently where there was only 5 sold in the UK.
A great find and certainly a rare bird!
I have a mate overseas rebuilding a YB6 and Bimota build quality is just stunning!!javascript:void(0);
From what I understand Bimota use a lot of Yamaha parts in their builds, switchgear, clocks etc.etc. so
the wiring can't be much different to a std fj1200 loom?

Hi, i should have been a little more specific in my post. What ever brand of motor Bimota fit to their frame, they also use the matching loom and switchgear, this makes for an easier transition for them, so when you look closely at the pics, you will see FJ switchgear, dash and loom, Bimota do have to modify the loom to make it fit as the FJ is a much larger bike than the YB.

Hi bikemad,
yes you are correct, it is a modified FJ loom.... I might be on to an original YB5 loom, so if i get it, i'll fit it to the bike to get it up to the race meet in March, then i might pull it out and have an auto elec, use it as a map for a new loom...
Good news really!
That makes the job a lot easier and something you can do on the bike, shortening wiring is not that difficult.
Fiddly and long winded but doable.

Wiring looms are not insulated, secured, wrapped and routed randomly, it is the result of much testing and experience. Small volume producers like Bimota would not have the facilities to test this sort of thing.
IMO
Besides that, it's proof of its Italian heritage. :biggrin:
