Found this Yamaha YZR500 two-stroke GP replica on the NK Racing website and we think the bike is pretty neat. The aluminium twin-spar chassis is from a reverse-cylinder Yamaha TZR250, the engine is a heavily tuned Yamaha RD500 YPVS unit and the suspension is Ohlins – forks from an Aprilia RSV Mille R and rear shock from a Honda CBR600RR.
The YZR500 replica rolls on 17-inch Marchesini wheels, shod with Michelin Pilot Race rubber. Brakes are Brembo units – twin 320mm discs with Brembo 4-piston calipers at the front and single 210mm Nissin disc at the back, with a twin-piston Brembo monoblock caliper. The fairing is based on the 1994 Yamaha 0WF9 YZR500, which Luca Cadalora rode to a second place finish in the 500cc world championship that year. The exhaust system is custom-made and the instrument panel is a fully programmable LCD unit from Translogic.
We think this YZR500 replica is, quite simply, rocking! Visit NK Racing for more details.
And here is Mr Cadalora himself, in action on the real YZR500
