Question What are your ride height changes?

I'm looking for feedback on people's ride height choices for the RC51. What I'm talking about is your tire choice (stock 190/50, 190/55, 180/55), adding a shim to the rear shock or adding shock length height to aftermarket rear shocks, and any changes to raise or lower the forks in the triple clamps. Mention your changes if any to ALL three as each on has an effect on the other.

With a good response this can be a useful resource to the forum.

What are you using on your bike. If you have tried various set-ups, please explain what they were, advantages and disadvantages, and why you changed.

I was going to raise my rear shock length/height 3-4 mm over stock, but I'm not sure this is needed with a 190/55 tire as the tire already increased. Information here will help me decide how I set up the bike.

Also read that a 190/55 is about 3/4 inch higher than a 190/50. Can anybody confirm this? That would mean about 8 mm higher in the rear.

Thx

I haven't made any measurements and can't now - but my forks are a bit shorter and the rear quite a lot taller. I had to add about an inch to the side stand... No problems with the steering (no damper required - for me, anyways) and considerably faster steering than std.
I like to be able to flick a bike into corners, not to need to gently lean every time. Lots of tight twisty roads in Japan.

Whilst i agree that in principle this could be a good resource, in practice there are too many imponderables, there is no substitute for putting the hours in finding what works for you, on your bike.

Is this for a track setup, or street setup? I guess I'm also asking if you would use this setup on only a street bike. I did some quick measuring on my new ohlins rear in the box and if it set to stock height from factory, you are basically showing one thread more than stock, or about 1 mm more. Does that sound correct?

I will be confirming the ohlins shock length to stock when I put it on. Hopefully in the next month to two.

Even though a single perfect setup does not exist for everyone, it is worthy of discussion and comparisons. Ride height setup isn't black and white but just because it is shades of grey doesn't mean it isn't something worthy of discussing. In fact, it is worthy of more discussion because it is shades of grey. Considering that handling is probably the most important part of a sport bike, ride height changes are one of the most important ways to set up and improve bike handling to personal preference, and it is doesn't cost a cent. This is worthy of far more discussion than many other topics imo.

I posted this to hear about how people have set up their bike, and what specific improvements to the handling it did that they specifically liked. The major considerations in a setup should come out in their post description.

At the very least, with this information I and others can use it as a beginning baseline for changes. Better than starting with a complete shot in the dark.

For a forum where there is so much discussion about how the RC51 needs a better shock, needs fork work, needs gearing changes, needs a 190/55 tire, it is mind boggling that many on the forum don't even bother with ride height changes or take the time to experiment and track their ride height setup. Handling is generally the most important part of riding a sport bike, and ride height changes should be performed and tracked, before adding mods. Unfortunately, this is reality on pretty much any sport bike forum, where people do lots of mods but don't bother with basic handling through ride height adjustments.

We had this discussion a while ago and no one knew there set up.
So I will start.
I will put up some numbers of my current setup.
2005 SP2:
Front, SP1 forks, 1K 280mm spring, very short top out spring, traxxion compression and rebound pistons, 7.5wt Silkolene RSF oil.
Rear, Penske, 326mm lenght, with a DK link and 600# spring with 17mm preload.
740mm front fork lenght.
Trail 98.6
430mm swing arm height.
Sag, 30mm front and 25mm rear.
Front 239 lbs, rear 228 lbs
These are static measurements.
Dunlop 211 ntec tires 190/55 in rear and 120/70 in front , soft front and medium rear.
Either street or track. I just need to tighten the sag, compression and rebound for trackdays.


As for the feel. The bike needs to be ridden it does not "fall" into corners but does what ever I want it to do, when I want it to. Great stability on the brakes and in and out of the corners it will slide as need and a backs in comfortably.
