    Are there still 2 piston choices (A+B) for a 2001 CR250  from Honda?

    13101-KZ3-505 – A

    13102-KZ3-L10 – B

    Most aftermarket companies do A,B,C and D and some E increasing in size increments of 0.01mm

    Thanks Ian,

    I was not sure if Honda had done away with the 2 sizes like they did with the CR125.

    What about cylinder to piston clearances?      .06  to .075mm?

    Nigel, Not sure who told you that Honda discontinued B pistons for the CR125, but it ain’t so!! A and B still freely available.

    Yes, 0.06-0.08mm is fine for the ’01 motor.

    Best Regards

    Thanks Ian

    when I was rebuilding a cr125 a couple months ago,the Honda dealer advised me that there is only an A piston available as the B piston had been superceded by the A piston.After getting off the phone with Honda today I asked him about the 2001 CR250 pistons,same thing, only an A available.

    I guess in Canada it is A only.If I end up needing a B I will have to buy from another country and have it shipped instead of picking it up in person.

     

    Merry Christmas everybody!

    Not sure I believe that? As far as I’m aware Canada is supplied Honda Parts Via American Honda Motor Co. and the dealers use their Fiche.

    Here’s Rocky Mountain Honda Powerhouse . . . . .Calgary

    Here’s the link. Just click: http://www.rockymountainhondapowerhouse.com/fiche_section_detail.asp?section=2497108&category=Motorcycles&make=Honda&year=2001&fveh=131955

    Sounds like you got a lazy parts man who doesn’t know his supersessions

    Piston A 2nd Item down

    Piston B 4th item down

    What can happen is they see the A piston has changed to 13101-KZ3-505 from 13101-KZ3-L10 and expect the B to have changed to 13102-KZ3-505 from 13102-KZ3-L10, but probably Honda have a bucket load of the old B’s left so the part number stays the same until they run out. The parts man types in 13102-KZ3-505 and of course it doesn’t exist!!

    I can’t see why you can’t obtain anything on that fiche. If your parts man is giving you grief, just try Rocky Mountain and see if you get the same answer. Quoting the part # always helps, but of course the onus is then on you to get it right!

    Best Regards
