StreetKORE Project: XS650 StreetRACER

XS650 StreetRACER

A new project is in the works here in the StreetKORE Garage. I’ve run out of catchy names at the moment and I don’t want to put some obligatory classification on it that really doesn’t fit. Frankly, I’m over that crap anyway. For now, it’s being dubbed the StreetRacer. It’s a little bit fighter, a little bit cafe, but mostly it’s a whole bunch of cool wrapped up in something that vaguely resembles a Yamaha XS650. And that’s good enough for now.

Frame: ’79 Yamaha XS650, Back halved, Braced, Monoshock conversion, Floating Subframe, Deluged, smoothed, tunneled for chain clearance. Engine: ’79 Yamaha XS650, 750cc Big Bore, Megacycle cam, mild head port, 2-1 exhaust, Mikuni VM Round slides, custom electronic ignition.


Front End: Triumph 955i Forks and trees, Akront 17×3.5 spoke wheel, Triumph 900 Legend rotor, Tokico 4 piston caliper on custom mount. Rear End: GSXR750 Swingarm, Hayabusa shock, custom adjustable linkage, Akront 17×4.5 spoke wheel, Triumph 900 Legend rotor, Vmax rear caliper and bracket with custom mount.


Body: Honda CB400T fuel tank, custom mounts, custom steel seat pan/tail combo, Lights TBA. Misc: StreetKORE Clip-on bars, K series GSXR rearsets on custom mounts, Right peg folds to clear kick start lever, 5/8″ offset Ft sprocket. Still much work left to be done. Future plans are for the PMA swap, make the tank and tail one piece, as well as the rest of the 1000 things on the check list. Will update progress as it happens. Also keep an eye on for future updates and other XS650 and custom projects.

    Looks like a fighter to me. For the Big bore, did you use the stock jugs?

    Looks like you know your stuff. It’s going to go like a father raper when it’s done.

    Thanks for the comments everyone.

    Yes, they are the stock Jugs. We got the bike with the big bore already done. It was an older project that the PO did some years back. It needs to get opened up and inspected, but compression is still good and doesn’t sound like anything is catastrophic. So that’s a plus. Right now the focus is finishing up the frame mods and getting everything clean and straight before I tackle the engine.

    boiiiiiing! I’ve always loved the way vintage bikes looked in this style. Very aggressive. I’d build one if it fit my riding style……

    Such a mutt, everything in the rear is perfect so far. Love this bike.
