'Seeley-Suzuki' 500cc Replica Racing Motorcycle
Registration no. not registered
Frame no. none
Engine no. T500 - 102733

The machine offered here consists of a replica of the frame built by Colin Seeley to house the Yamaha TD/TR twin-cylinder engine, which in this case has been fitted with a Suzuki T500 motor. Seeley's Anglo-Japanese hybrid was known as the 'Yamsel', and the first of them enjoyed considerable success in the hands of John Cooper.

The machine formerly belonged to the current vendor's disabled late brother. A race mechanic, the brother started buying Suzuki T500s in the late 1970s and then bought the Yamsel replica chassis. He wanted the Seeley-Suzuki to be raced at the Isle of Man, but after 25 years trying to build a race bike out of the Yamsel chassis and a Suzuki T500 engine, he had to take early retirement due to a serious heart attack. Sadly, he passed away four years ago with out finishing the bike.

The vendor then took it upon himself to finish the project on his behalf and completed it early this year. Since then the freshly built machine has not been used apart from a gentle set-up session at the Tonfanau circuit in July of this year, where it went well. Included with the machine is a selection of spares and equipment ready for the new owner to take the machine racing should they wish. Highlights of its specification include:

• Maxton forks
• Yamaha alloy wheel rims
• Twin front brake discs with Girling callipers
• Single rear brake disc with Girling calliper
• Adjustable rear shock absorbers
• New Scitsu rev counter
• Keihin carburettors
• Premix lubrication (no oil pump)
• Freshly built engine, everything new or refurbished
• Crankshaft lightened, balanced and Tuftrided
• Alloy crankcase stuffers fitted
• 750 con-rods
• Balanced pistons
• Crooks squish-band cylinder heads
• Electrex electronic ignition
• Close-ratio straight-cut gearbox
