I consider the RZV500R to be the granddaddy of all Yamaha road going two-strokes. Grand Prix inspired 500cc water-cooled, twin-crank V4, full bodywork, four exhaust pipes exiting out the rear, a 16" wheel in front and 18" in back. I coveted every magazine article and sales brochure featuring these machines for ages, eventually purchasing this one bone stock nearly 20 years ago. As you know the RZV500R is the aluminum framed, detuned Japanese home market model, and has subtle features that are uniquely Japanese: The controls, the gauges, the domestic decals. I like that. But for those that have ridden this bike in stock trim, you know how ill-equipped this chassis is for this motor. So I upgraded, or shall we say modified, the swing-arm, forks, triples, brakes, and 17" wheels to 1995 YZF750. Installed a Penske shock and did the CDI and Carbs. And I had to bolt on a set of Jolly Moto Chambers. Better, safer, faster... louder? My goodness the sound of those Jolly's---like a Gatling Gun on Crystal Meth.
