No. I had the bike-quip risers. I needed to slightly re-route the brake hose - ie unclip it from under the bars, but the throttle cable was not an issue. Check the workshop manual - it has diagrams in section 1 showing the routing; make sure that there is some free play in the cable - maybe someone has adjusted it all out - and a slight change in routing will make the inner cable even tighter - you can adjust the outer cable at the throttle grip - the metal tubes, and at the throttle wheel under the airbox.Just fitted the rises there bike-quip ones every thing feels good apart from the throttle cabels when in hard left lock there very tight is this normal?
