cr80-cr125 engine swap

[hondacrrider]

i have a 96 cr80 and i was wondering does anyone know if its possible to put a cr125 motor in the 80 frame?

[89shee]

anythings possible man . just takes fabbing up. a buddy of mine picked up a 89 cr80 with a 94 cr250 engine that thing is a beast!!!

why wouldnt you just want a 125? Im riding a 1999 yz80 and I love it but I feel like it doesnt have the suspention and power I want.

[Duneman101]

yeah anything is possible, a long while back someone posted a kx80 with a kx500 motor in it... i can't even imagine riding that SOB. are you looking for more power in the 80 body? or are you just creating a little frankenstien.

[hondacrrider]

i like the size of the 80 like its light and easy to throw around i just wanna find a way to gain alot more power in it

[kxrider]

yea its possible jus with sum fabbing and i kno what u mean i love my kx80 for its size but its not enough power but tha problems u are going to come across is cooling im pretty sure most all 125's run 2 radiators 80's run 1 also 80's down tube fans out at tha bottom and a 125 forks bout half way down for tha exhaust umm also idk what size chains are on 125's but i kno there are bigger than a standard 420 thats jus a few thing u gonna need to address also make sure u have enough head room so u can replace ur piston with tha bottom end still in frame makes it easier another is ur exhaust pipe

my dad used to have a kx60 or 65 or whatever size that was. with a kx250 motor in it!

it was so fun,.

i was able to take a little tiny kids bike and whoop my other girlfriends on there blasters and banshees on it.
i thought it was hilarious.

but they do wheelies a LOT

im not completly positive but i think service honda did a convrsion like this it might have been with a cr 250 motor though

A 105 big-bore kit would be cheaper, easier, and have better resale value when you are ready for a big bike

[dmartin1]

well if he doesnt want to sell it i think he should throw a cr125 motor in it.
sure the 105 big bore would make more power.

but that cr125 has more potential then just the 80 does.
