Just installed the new speed master tune 2, what a difference!

Before the tune my bike had touchy acceleration, which is not great for cornering or roundabouts. I always had to ride the clutch to smooth it out. First test drive with the new tune and that problem is gone, smoothest acceleration ever.

I highly recommend this upgrade, just make sure you follow EVERY instruction to the letter. I wasted 1/2 an hour because I didn’t read the bit about the usb port.
