    In 1993 and 1994, Harris Yamaha's (SRX engine) won the British Singles Championship (Steve Ruth 1993; Dave Rawlins 1994). 1994, Jim Moodie won the inagural Single Cylinder TT on a Harris SRX.

    This Harris SRX is frame No. HPF1206.

    I've owned and raced it, occaisionally, in AHRMA (SOS2), AMA (Mid-Ohio) and WERA (Clubman) since 2007. The frame, wheels, suspension (Ohlins shock) and brakes are TZ250 spec. The engine is built with +1 mm Arias 10.5:1 pistons, Megacycle cam, valves and springs, and oil cooler. Twin Mikuni flat slide carbs. 54 RWHP on MSP Cycle dyno.

    It weighs nothing, has God's own brakes, handles like a GP bike, is sized like a GP bike (it does not fit me at 6'-2" and 200 lbs, and arthritis and multiple crashes no longer allow me to fold myself into the bike). It is a FUN bike to race.

    The bike comes with gearing and some spares (footpegs, levers, clip-ons, brake pads, fork seals, belly pan for use without fairing) and the side stand shown.

    $7,995 in Talking Rock, GA. It will be at Barber for the AHRMA races and Vintage Festival Oct. 7 - 10.

    So is this an SOS1 bike in ahrma or SOS2?

    SOS2 with bump up to SOS1. SOS2 is water cooled 450's and air cooled 600 cc 4 valve singles. The latest and greatest 450's are making really good power and their powerplants are light and compact. The hot ticket would be to put a modern 450 water pumper in the Harris frame and destroy the competition. Plumbing up a radiator might be a challenge due to space limitations, but 2 small radiators outboard on either side would probably do well. For a vintage bike it goes quite well, and I'm confident a better rider than I could really show what it can do. If you wanted, I'd entertain selling the bike without the SRX engine that is in it - it is a good piece and I can put it in a SRX street chassis I have.

    Cheers,

    For clarity, SOS1 in AHRMA is dominated by KTM 690's (Husky 701's) and Kramers. 75+ hp and handle like GP bikes. But, unless you have $20,000+ to put into a singles racer . . . . .
