Crankcase for the Yamaha R9
Why choose it over the original?⤵️
• The original protrudes significantly from the bike, which is a problem on some tracks where it can rub against the ground when cornering. The Spider crankcase is lower and eliminates this risk.
• The original is a single piece, so to remove the alternator, you must drain the oil from the engine and then remove the part. With the Spider crankcase, you only need to remove the outer part.
• It is made of billet aluminum, so it is more resistant.
It is also compatible with our engine protection (20.Y319), which can be mounted on top and is the same as that used in the Supersport World Championship.
