Claire M. ★★★★★

Took the bike out for the first track day since installing these, and the mid-range pull from the 11.3mm intake lift is exactly what the GSX-R was missing. The valve spring set kept things quiet at high RPM, which I was worried about. Just make sure you have a good tuner to dial in the duration.

Amelia ★★★★★

The 11.3mm intake lift really woke up the top end on my '19 GSX-R, and the included dual valve springs gave me peace of mind during installation. A solid upgrade for anyone chasing more mid-range punch.

Kevin ★★★★★

Dropped these in with the stock sprocket and the exhaust cam timing feels spot-on out of the box. The 9.2mm exhaust lift is a solid step up without needing to clearance the head, and the dual valve spring set gives me peace of mind at high rpm.
