Weighed the rear compared to my BMW OZ racing and 2kg+ heavier, so doubt they're much if any Lighter than std zx10r.

11.9kg vs 14.1kg with Superbike slicks and no sprocket carrier. Weights might be a little off as I wasn't using a proper hanging weight scale but the rim is noticeably heavier.

Great updates!

On the steering damper, websites call for an SD 021, but the kit manual calls for an SD 001. It has 3mm more stroke. One of the parts to mount an SD 001 (collar) is no longer in production, but I've a spare if anyone needs it.

Really interesting about the wheels. As far as the pistons and crank goes, were you able to verify that the pistons are higher compression? I'm really curious about the differences. I'm wondering also if the crank was modified for the crankcase, or if it was made stronger / lighter in key areas.

So many questions!!

Compression ratio is the same. I was told they are lighter but don't have exact measurements. Aside from that there's no difference for the pistons.

Glad I didn't spring for the RR wheels!

That is strange! In another thread one of our other forum members was stating that the wheels were specially made for the RR to specifically be lighter then the production wheels carrozzeria makes. I wonder what / if if there is a difference

I've read the same post that they were 1lb lighter than the aftermarket light weight wheels but think it's actually 1lb lighter than standard zx10r. It's doesn't actually say in that they they are suppose to be lighter it's just says lighter turning and lower moment or inertia...lol. Just used a floor scale so could be off a little but they're noticeably heavier just lifting.

Thai race mechanics said the same that the pistons are lighter but look the same.

Also noticed front master cylinder and brake calipers are different part # to zx10r.

Hmm, no mention of different brakes anywhere. I'll have a good comparison between the two this week. Going testing and one of the guys is on a new RR, was on a regular 10r last year.

The thai Kawasaki riders here have been racing the bike since Jan. One rider said the engine does feel stronger stock and the top speeds were a little higher back in Jan when they first raced the bike. But I've heard one of the top British Superstock riders tested them back to back and couldn't notice any difference.
