Ultra light rods & pistons

Anyone tried JSmotorsport Ultra light rods & pistons? They are a special order thing. The ultralight rods are down to 95 grams on the small end and the 750 ultralight pistons are lightened down to 170 grams. The 850 pistons are down to 190 grams. Its an extra charge to get these parts Ultralightened.

Lots of us rich kids and poor racers have. Best there is they say.
Special order here to keep his stock fresh please.

You must have a few more km on it now that summer is over......how is it going?

And what is the long winter plan?

I'm familiar with the JS lightweight rods & pistons - I have been riding quite smoothly with them for over 30,000 miles and the motor still goes like new.

But I'm talking about the ULTRALIGHT rods & pistons. These rods are lighter and are only for 750s up to 80 hp. The pistons are lightened even further.

The ultralight rods are down to 95 grams on the small end and the 750 ultralight pistons are lightened down to 170 grams. The 850 pistons are down to 190 grams. It costs extra to get these Ultralightened goodies. The website says they are for solid framed bikes but has anyone tried them in a Commando?
