[QUOTE="andrew peters, post: 93838, member: 3776"] I've been following this thread with interest and have researched this subject (and other ideas to improve my Rapide) almost to death! I'm nearly finished putting disc om my bike and feel it's about time I threw my hat in the ring as I may be able to help a little, after all, without the help of you lot (Vincent riders generally) I would have even more to work out by mainly guesswork.. So like I said I'm not completely done yet but I can keep you all posted, I'll even take some pictures later (soon) Discs.. yes Honda 250... 'correct' offset and 5 hole pattern, centre bore is about 20 thou small. easy. I drilled 5 more holes and made a thin sheet ally cover ring for the other 5 holes, I trimmed a flat off a set of 5 new bolts as you need slightly long mounting bolts. I then made ally plates to support the stock speedo drive and hide the Honda disc centres. I had to build a boss to move the drive box outboard slightly but the gears line up now. Also on the 'cover' plates there is a boss to line up with the fork leg stop, this boss is centre bored to locate with the caliper bracket 'stop peg' I used Kawasaki Zepher calipers (I would have like opposed piston calipers but I need spoke clearance and moving the discs out I lost alignment for the speedo drive) as the mounts on the caliper are not handed, only the floating two piston caliper, which has a bleed nipple at the top for easy bleeding. The caliper bracket is 6 mm ally pivoting on stainless counter-bored spacers on the new 4140 axle. 'stop pins' are also stainless locating on special 'top-hat' threaded plugs that locate into the brake disc cover plates (the cover plates don't really rotate as they are held but the axle tightening but I figured they would be better pinned as the speedo drive needs to stay in one place. (the left side disc cover is just a cover.. although in black with un-drilled disc is does look a little less modern) The front fender stay is bolted in the same place on the fork leg, the bolt going through the caliper bracket as it may stop the caliper dropping down, but its not in any tension either way. the other fender stay is off a welded lug on the caliper bracket, I didn't like the fender stay going around or bending over the caliper. My ideas aren't totally original I admit, like I said I research a LOT before using the best ideas and making them work for me. It really is quite a bit of work but I believe it looks and should (I've not tried it yet on the road, other work I'm doing as well, including Normans Steering head mod and AVOs) Yes, I know someone will ask for pics and I will post some. While I'm here I will thank Everyone in the VOC and all Vincent owners for being so willing to share their experience and advice.. believe me, it's valuable and appreciated, and a lot more useful than the nonsense I've read on Harley and BMW forums, (yes, I have a couple Harleys and a BMW, old bikes not those new fangled things!)
