2007 yamaha r1

[POWERHOUSE]

Two Brothers undertail slip-ons, stock air filter, custom dyno tune (PC3usb) and Ecu Unleashed flashing, all done in-house . . . might not be the world record for a stock motor, but it is the most we have seen so far on a cross-plane Yamaha . . .

Uncorrected was 172 @ 84 . . .

A whopping 135rwhp

I guess the cross-plane crank was a track oriented design&may have worked as intended, but on the street I always thought they sounded like crap and were pigs on the top end. We had bolt-on GSXR 750s that were geared giving those R1s fits from a 60 roll,on the Mexican hiways
