hmmm its all about the rider... and how the way he rides his bike... i can tell you mine but it might not suit ur way of riding...
first thing is to set up the suspension stock suspension on the K5 are fully adjustable so u need a preload adjust and a flat tip screw driver for the rebound and compression... for me i set my rebound 7/9 clicks, compression 6/9, as for the rear my rebound is adjusted by my mechanics.. i have no idea
tyres u can get super corsa or the new pilot pure.. not bad... and it cost 35rm on weekdays and 50 rm on week ends and 85 on track days...
