K0 to K1 Seat Pan: Does it fit K2-K5?
My gf purchased the seat pan for me on her last trip to Japan to save freight back to Australia. I am planning to build a custom seat for a resto-mod CB750 Cafe Racer build, retaining as many original features as I can due to the increasing popularity of this famous bike/model and value. Although I could not get any information on whether this seat pan fits the K2-K5, I thought it looks very very similar and so would take the risk. Having now done a trial fit, here is the conclusion:It fits with three minor modifications:-one of the holes in one of the hinges on right-hand side of the seat needs to be expanded slightly to be able to locate the bolt into the nut welded on the upper side of the seat. The other three bolts fit their respective nuts perfectly-the rear edge may need to be reduced by approx 5mm to provide adequate clearance with the rear mudguard-the seat post needs a completely new mounting position on the seat pan as this does not line up with the K0-K1 mounting position. Easily done with some careful cutting of the cover which is spot welded onto the seat pan and drilling two new holes, plus preferably welding nuts in place.So, it fits with the above minor modifications.Paul
