Here's a mod I did to a Yamaha that used the same long twist tube as the R7. The progression helps with low speed throttle precision by opening slowly off idle and quicker at wider throttle positions. I suspect many R7 owners will just replace theirs with a stock R6 tube for a shorter twist.

I’m probably going to find interest in the unmodified R6 throttle. A lot of us put a ring insert on our throttle tubes of our TLR’s to bring the full throttle twist from about 94 degrees to about 72 degrees.

It was helpful on track to have the whole motor in your hand, as some folks had to reposition their grip to get 100% throttle.

I had the shorter throw on mine and didn’t have any problem with throttle precision. It was fine even on a wet track day. 👍

The progression is good for city traffic. In first gear, it's smoother feeling at low revs if the bike makes gobs of low end torque. For a street-only bike, it's better than stock but not as agressive as a short-throw. The plastic carves easy enough but I'd also try the stock R6 tube on the R7 before making another. It works for the Bolt because it makes good torque from about 2000 rpm.

What range of years for R6 throttle tubes would I look for if I wanted to try this on my R7? Thanks in advance!

I'm pretty sure the TL came stock with a progressive throttle but it's done at the pulley on the TB instead of at the grip. You can tell by the oval shape. Other bikes came that way also but not the MT07.

Thanks @EDS I ordered one of those today. I'll let you know if there are any fitment issues, I don't think there will be. Have a good weekend. (y)
