Throttle grip

[parillaguy]

I discovered the rc390 has a throttle tube that is made of plastic and it has ridges at each end that keep the grip from moving. The throttle tube is also shorter than almost all of the replacement grip sets I tried. I have never seen a throttle like this and was wondering if there is an aftermarket grip set that fits? Any suggestions? Parillaguy

Most grips should fit. I filed and sanded the ribs smooth and then installed BLK/Orange KTM open ended grips.

I would install a G2 Quick turn Throttle and Renthal Grips from MNNTHBX, I did and it makes a big difference in throttle control. 1/4 turn to get to wide open.
