    Looks like a standard kit to me except the picture of the exhaust ,but it clearly states a chrome exhaust where as the pic is different ,I can't tell you much more than that without eyeballing the motor

    58cc is the 45mm piston. Might be better to stick to 48cc or 66cc as easier to get parts.
    Otherwise standard kit. Exhaust is a little different.

    Quite clearly says in the description:
    18. (66cc / 80cc for SkyHawk ) Cylinder Head Cover

    19. (66cc / 80cc for SkyHawk ) Piston

    20. (66cc / 80cc for SkyHawk ) Cylinder Body

    so idk. Might be a misprint.

    Interesting... didn't know there was a 'middle' size between the 49cc and 66cc.. at first I thought they were mislabeling a 49cc as 58, the way many vendors call a 66cc an 80.
    It might be a misprint, but I'd side with Theon and go with a "known" size for the sake of getting parts.

    I have a 45mm piston/barrel here.
    It was a '70'cc motor, it had 40mm stroke in a 50cc case(6mm head studs).
    I made it in to a 69cc but had to widen the barrel opening in the cases and redrill and tap cases for 8mm studs.
    If any one is interested the piston/barrel and rings are in new condition, and probably hard to come by. I do not need these, I have offered them to Sub, who hasn't taken me up on them.
    If Sub don't want them, I would be happy for them to go to a better home.
    P.M. me if interested.

    I think it's suppose to be a 55cc engine. They were popular as Hop-up kits for the 48cc engines. Here's a side-bar post from the website that leads me to believe they're 55cc:

    "bought a new 55cc engine pre-installed on a brand new mens bike from Colm for 590 euro. not bad for a new mountain bike and a new engine! looking forward to my daily commute no..."

    "It's extremely reliable, requires virtually no maintenance and can do up to 50 miles a day comfortably''
    Obviously not a truthful ad.
    I'd avoid it.

    From what I have understood is that there have been 48 49 55 58 60 66cc engines back when Spooky Tooth was actually Spooky Tooth and not Bike Berry as it is now, they had a pic on there site showing an identification of each motor.

    Except for the exhaust, it looks identical to a 66cc China doll. And as dodge pointed out, they show the top end specs. I call misprint on this.

    Here is something that was posted on the old Spooky Tooth web site, I realize the engines shown here are not all available anymore and this was likely done before the slant head 66cc engines came out and also, I have a 66cc engine that has the 6mm studs that isnt represented here in this but I figured there are a lot of people who have never seen this so I wanted to post it here in case someone comes across an engine they are having a hard time identifying.

    There you go, thanks Map'.
    So does anyone want this 45mm piston and barrel?
    PCD of bolt studs is different to 66cc!, I presume it may be the same as 49cc.
    PCD (across diagonal) is 60mm on 60cc and 63mm on 66cc.
