Question Rear shock or slipper clutch?

Looking to upgrade the track worthiness of the F4, I have a friend who is offering me a very good deal on a slipper clutch but I'm also interested in a ohlins or similar rear shock and I can't decide which to do first. I will likely only be able to slip one or the other past the wife for this season, so what say you guys, should I do the rear suspension first or pop the slipper clutch in?

What we've got here, is failure to communicate.

If you have your suspension set up for the track by a suspension guru, you should be able to get good service out of your stock shock, provided the spring is correctly sized for your weight. If not, it's not expensive to put a bigger spring in the stock rear shock.

Having bounced the rear end of my track bike on heavy braking / downshifts going into corners, I couldn't wait to get a slipper clutch. The slipper clutch and the quickshifter are the #1 and #2 mods I've made to my track bike, after getting the suspension set up correctly, using the right sized rear spring.

Easy answer. If your goal is faster lap times, you must do the suspension. A slipper clutch will not give you lower lap times if the suspension doesn't work for you!

Rear shock.

It ain't what you ride, it's the way you ride it.

slipper - it will reduce the strain on the gearbox and/engine on over-rev/downshifts when at track.

The stock suspension is going to be good enough (if the spring rate is right) to carry you through to A group riding level. Get it set up and you will be good for a while.

Having a slipper clutch was one of the best modifications I ever did to my bike. Now when I am entering turns, the bike is more settled because the rear isn't hopping all over the place. I was able to drop quite a bit of time off of my laps thanks to the less hectic corner entry.

Looking from a different perspective, if your ultimately going to do both mods take the great deal on the clutch it may not be available in the future.

All of this is great advice and what certainly what I would recommend, even if that slipper clutch is a good price.
