749 to 820cc!
This thread is dedicated to our drop in GT MotoCycles® 820cc pistons for any '09-16 V7 models - click pic below for details or HERE. We will offer GTM® flow-ported heads for even more power.
I may also offer a cylinder core/swap for a complete turn-key kit, but if you're interested in it short term, grab the pistons now, and I'll honor the kit cost. Lead time once these are sold out is ~12 weeks.
Dyno graph below shows stock V7 (blue trace - 36 rwhp), GTM 820-2V (green trace with ported heads ~45 rwhp -- and below for ~51.5 rwhp) and GTM Quattrovalvole @749cc (no longer available ~55 rwhp) or see our GTM Quattrovalvole 820cc @~67 rwhp) dyno HERE.
Newest graph below on our in house Dyno with a 2015 V7, GTM ported heads, GTM 820cc 2V pistons and our GTM 2>1 exhaust:
