what are some motors to put in the raptor 125 custom maby like a raptor 250 motor? or a custom 2 stroke motor?

look down in this section for posts by exhausted.. he has an rm85 in a raprot chassis.. I have also seen yz85, ktm85 and crf150r motors in them.

Yes, and 85cc 2 stroke motor is probably the easiest and makes way more power than the 125 4 stroke. only real tricky part is getting the pipe to fit.

i heard that the raptor 250 and 125 frame ar same just bigger motor would the 250 raptor motor fit in there nice and easy? just thinking ahead 1/2 years from now im gonna put a custom motor in or im gonna do a lot of internal motor work

I believe the YZ engine is the easiest to fit in the raptor chassis only because of the exhaust fits a little better.... CRF 150 are bad *** though!!!!

you need to look at what class you want to run the bike it and then decide. if your looking to do 70cc open then a cobra or kx65 with Athena 72cc bb kit is best. if your looking to do open 90, there are a ton of options. but the truth is as I mentioned. you need to pick a class then re-ask what is the best more in the bike for that class. 150 puts them into super-mini. so if your looking to move into that class, the other option is a 105cc 2-smoker. and I hate to say it, but if I had to chose between a 105 kx or something vs. a 150, I'll take the 105 every time. twice the power in my opinion. I would again recommend KX, cobra or KTM. Reason not a Honda is there seems to be some issues with Honda at that performance level and the fact Honda keeps making changes every 2-4 yrs on a motor means very limited parts. ktm and kx both have some nice aftermarket stuff including Athena. (in my opinion the best starting point for any serious performance motor. flows way better than stock and cools tons better. then get it ported and BAM!!! your set.) anyway, good luck and let us know the class.
