Not many pictures of NSR500 or 500V engine parts on the internet so here are some from my rebuild. I'll add more as I dig bits out.
2001 spec engine with revised crankcases, uprated gear box, clutch and clutch cover as well as nitrided output shaft collar. Det rings in both head and barrel. Magnesium water pump, clutch cover and exhaust manifolds.
Tungsten crank with heavy metal inserts. Ceramic centre bearing.
