PORTUGUESE 2-STROKE SPIRIT !
YAMAHA RD 500 V4 ( 1985 )
The legendary V4 500 2-Stroke GP Race Replica from Yamaha, the Yamaha RD/RZ 500.
We've always dreamed about the 4 cylinder 500cc Grand Prix bikes, and having the opportunity to acquire and ride a replica made for Road/Street use was a tremendous experience.
So, in 2005 we've bought this precious bike and tuned it with RacingSM specifications.
This Yamaha RD 500 V4 was imported to Portugal from Australia in the late 80's.
