High Compression Piston for SM450

[emildev]

Hi,

Does anybody know of a manufacturer that makes an 13.X High Compression Pistion for a 2006 SM450?

check with fbf for your hi-performance goodies. I do imagine that motoexotica and g.p. cycles will have the same pistons,...cams available

Hi,

Had a look at fbf offerings, they do a 12.5, 12.9 is std on the 2006's. Im looking for a 13.1, any other ideas?

Best regards, Emil

Yes. CP Piston makes a couple different high compression pistons. I'm running a 13.5:1 compression piston in my '05 SM510 that has has had the larger '06 ti valves and seats installed.

When you talk to CP make certain you tell them you've got an '06 with the larger valves because the piston needs to be machined to clear the larger valves.

BTW, run a Sil header if you do the piston you'll get more top-end power where you need it.
