    Need Help Why would my top speed only be 140kph/90mph?

    75kg - I don't think its my weight that's the issue :)

    Need Help Why would my top speed only be 140kph/90mph?

    I've got a 2020 RC390 that's not performing as I'd expect. I never got to give it a proper test whilst stock, but after just adding the 3/4 R-77 Yoshi pipe (without a tune mind you) I can only hit 140 down the straight. It's my first bike so I'm too ignorant to know if its underperforming...
