    Hi All:

    It took a tremendous amount of work, but I was able to convince the original OEM of piston rings, Riken, to make me a custom run of replacement rings for the NLA inline 4, 250cc motorcycles. I have currently been approved to make any sizes of NL3 (Yamaha FZR250), and KAZ (Honda CBR250RR MC-22). I am waiting for some Kawasaki and if any Suzuki parts might be of interest.

    I have to order a minimum of 200 sets (50 engines) of each size. So, before I have a lot of stock in sizes that people don't care about, could you guys please let me know the following:

    1): How many of you are out there that are hunting for rings?

    2): What are the most used sizes of rings; STD, +0.25, +0.50, +0.75, +1.00?

    Looking forward to a response ASAP.

    Hey Rossco_Perth. What bike?

    Prices will be about $38 USD/cylinder. Remember these are the REAL DEAL OEM Rings, not Chinese knock-offs
