well i had the the penske on my F3 and loved the damn thing so i put one on my 600RR good rig i have no prob with it. but as far a penske VS ohlins it's what ever name you want it to say on it. i have ridden a 600RR with a ohlins on it and i cant tell feel much diffrence in them. But if you want to spend less money try RACE TECH they make a kit for the front forks and the back shock.I used race tach for the front forks on all my bikes.but on the 600RR you can put 1000RR triple tree and the forks!
