Offered from the estate of the late Clifford Jones
Yamaha Rotax 690cc Supermono Racing Motorcycle
Frame no. ST-ROT-49625
Constructed using a Yamaha TZ frame and 690cc Rotax five-speed engine, this supermono racer was completed in its current form by the immediately preceding owner in 2009 following some 100 hours in the workshop. Work carried out to get the bike race ready included replacing the original forks with a set taken from a 2004 Yamaha R6 and swapping the FZR400 wheels for lightweight aluminium TZ ones. The front brake has been upgraded with a 320mm PFM disc and AP Racing 6-pot calliper, operated by a Brembo radial master cylinder, while the rear disc is gripped by a Brembo calliper that started life on the front wheel of a scooter. The frame, sub-frame and swinging arm are powder coated, while the fairing, tank, rear hugger and Yamaha TZ250E 'droopy' seat were finished in two-pack paint. Other noteworthy features include new Vortex clip-ons, Dennis Trollope rear-sets and a Suzuki GSR600 K6 shock absorber, while the engine has been stripped, repaired and rebuilt by well-known classic racer, Steve Ruth. The machine was purchased by the late owner at Bonhams' Stafford Sale in November 2011 (Lot 442). A potentially competitive mount in the 'sound of singles' and 'supermono' categories, this smartly turned out machine is offered with a quantity of spares to include a 640cc Rotax five-speed engine. The rear-wheel paddock stand and a photocopied Rotax repair manual are included in the sale. No reserve.
