| I've never had one of these bikes so I could be wrong but, as I recall you could get a 748s Bip - one of the guys that used to ride with us had one. I think people get confused that the Bip is the lower spec 'standard' model and I don't think this is always the case.
Termis - could it be that JHP supplied the Termis? As far as I know JHP never had a set of their own brand zorsts.
Discs - I would be surprised if they're any bigger than the standard 320mm fitted to virtually every Duke otherwise all the caliper mounting points would all be different as well
Then again, I might just be talking ballcocks |
