Recently came across a copy of the August 2006 edition of PB magazine, where they’ve compiled a list of the finest two-stroke sportsbikes ever. We quite loved the story, and we’ve posted a few excerpts here. (While PB have compiled a more exhaustive list, we’re only posting what they have to say about their ‘best in class’ choices.)
[Best in class] Honda NSR250R
>From 1986 – 1994 >Top speed 192km/h (1989 SP model) >Power 45bhp@9200rpm (restricted)
Not the fastest or most powerful 250, but the most beautifully engineered. By a mile. Based on Honda’s delectable 250 GP bikes. Made Yamaha’s TZR feel like a fish and chip dinner.
[2nd] Suzuki RGV250
[Honourable mention] Aprilia RS250
[Best in class] Yamaha RD350 YPVS
>From 1983 – 1991 >Top speed 200km/h (F2 model) >Power 49bhp@8500rpm
The 350LC was seminal, no question, but the 350 YPVS (called the RZ350 in the US) was always the one that mattered. It had the technology: powervalves, perimeter frame and rising-rate rear suspension. Capable of leaving big four-strokes, including Yamaha’s own 240km/h five-valve FZ750, trailing in a sweet-smelling haze. A masterpiece then and now.
[2nd] Yamaha RD350LC
[Honourable mention] Yamaha RD400
[Best in class] Suzuki RG500 Gamma
>From 1985 – 1989 >Top speed 240km/h (tuned) >Power 86bhp@10,500rpm
The best 500 GP replica. Suzuki allegedly blueprinted the first test bikes so they’d do a genuine 240km/h. Neat trick. The legend has lived on ever since. Spindly chassis and laughably thin tyres were out of date from the start, but the RG’s motor has been the two-stroke special builder’s powerplant of choice ever since. With 100bhp well within reach, who can blame them?
[2nd] Yamaha RD500LC
[3rd] Bimota V-Due
[Honourable mention] Kawasaki H1 (Mach III) 500
[Best in class] Kawasaki H2 (Mach IV) 750
>From 1971 – 1975 >Top speed 200km/h >Power 74bhp@6800rpm (claimed)
Piston-ported inline triple with a fearsome reputation, but the handling was more frightening than the powerband. Inspiration for the terrifying H1R racer.
[2nd] Suzuki GT750
The RD350 YPVS is also PB’s ‘Best of the best’ among all two-stroke sportsbikes ever produced anywhere!
[Unreliable V3 engine]
[Restricted model, made in Brazil]
[3MA, Mk1 reverse cylinder model, ruined by lumpy carburetion and suspect reliability]
[Fell apart frequently]
