It seems almost fitting that this is the last week of testing for MotoGP before the winter ban sets in, and also that we discover that three Aprilia RSW 500’s (500cc 2-stroke GP bikes) are up for sale. These bikes were ridden by Tetsuya Harada in 1999, and in 2000 with Harada again, along with Jeremy McWilliams. More and pictures after the jump.
The Aprilia RSW 500 was equipped with a 498cc 2-stroke, two cylinder engine. It was liquid cooled and featured an electronically controlled Rave exhaust valve. Fuel mixing was handled by two Dell’Orto VHSD 42 carburetors, giving the bike 140hp of peak power at 11,750 rpm.
For the buyers of these bikes, other goodies include: 42mm Öhlins forks with double hydraulic control (hi/lo settings), and a rear Öhlins shock mounting to the carbon fiber swingarm (wipe the drool off you chin here).
The two Harada bikes and the one McWilliams bike will also include an Aprilia serial number confirming their authenticity, and come with an declaration written by Aprilia about their origin including race and result details.
Obviously these bikes are are not street legal, but they are fully functional, meaning you’ll be all the rave at your next track day. Point your browser to to Combattiva.it to make your bid.
