I've always felt the '70s Japanese too-smoke single-cylinder DIRT-bikes, need to ALL be re-built as ROAD RACERS, in the vein of an OSSA or BULTACO TSS etc. Check out the Honda Elsinore based MT125R to get an idea of what I'm talking about. The MT125R doesn't just beg for a follow-on "MT250R" but it's got me thinking about the biggest versions of Honda two-stroke singles, which were what? Something like 500cc or 650cc on some type of XL650L or whatever it was called? And there were BIG-BORE kits for that stuff, too - Wasn't there? Any problems with the chassis and just stuff 'em into the smaller SOHC-4 frames, simplifying the whole question of street registration. And if the Honda drum hubs aren't up to snuff? Skip straight past the wire-spoke conversion of the CBX550F Comstar "inboard disc" fake drum brakes aka FAUX-LEADING-SHOE as I've coined 'em - I've been tinkering with a GL1500 based version, though it's stalled in it's tracks and I'm now looking to the PC800 Pacifica for IT'S front wheel hub/core. Only 230mm rotors on the CBX550F whereas GL1500 was dual 296mm with potential for 316mm upgrade using GL1500SE rear discs, while PC800 is only 276mm but upgrades to 296mm with USA-spec CB1100F rear discs. That type of shit would stop ANYTHING, and they'll be a very strong & stiff version of a wire-spoke wheel due to their larger diameter 'spoke flange'. Though it's not truly a "spoke flange" per se. As much as for strength reasons as clearing between the rotors & calipers etc, we'd want straight-pull "NAIL" spokes - That would be most sensible in the GL1500 or PC800 version, IMHO. That way you're not adding any additional weight as in the case of the CBX550F version's ridiculous steel spoke flanges & assembly bolts etc, instead we're talking about wheel cores which are deceptively lightweight, they're just a thin balloon skin of alloy, in fact I'm more worried that it'll be too FLIMSY, rather than too heavy. These "Faux-Leading-Shoe" fake drums are powerful enough to stop ANYTHING. CBX or DOHC-4 based "Hailwood Replica" Yeah, now you'd finally have a brake that's as good or better than the best OEM versions, but you'd get the retro-fried look as well. Picture the Jap too-smoke single ROAD RACERS though. Even if you're gonna use first-gen disc brakes for a more mid-'70s aesthetic, we're talking about the PE350 & IT400 etc. Wasn't there an IT475 or thereabouts? There are a ton of these bikes rotting away in sheds all for the lack of NOS bits to restore 'em with. The dirt-bike kids regard 'em as JUNK when there's nothing left but an engine & frame. Well that's all we'd WANT for what I'M talking about here. Just picture it. Mull the idea over in your head. Mmmmmmm...... -Sigh.
