Hi all. There is a new hi tech rear drive chain out for sale. It is made of Titanium and is coated with Nickel Boron. The tensile strength is 11850 lbs the weight is 3.5 lbs per 100 links. So it is very light and strong. That was for the 530 pitch chain. The 530 pitch chain is $600.00 for the 120 link chain and $850.00 for the 170 link chain. And yes it will be on my LSR bike. I know going fast is not cheep!
