debating about moving onto bikes

2 totally different motors.....1 is a normal cylinder reed motor(01) and 1 is a case reed motor(02)and it all depends on who you talk to on which is better,alot of ppl like the older(01) motor better beacause they claim the 02 has less balls because of a to big reed area,and not as much bottom end but i have had both and yes the 01 has more bottom and so it feels stronger to some but i personally like the 02 motor better because of its strong midrange and top end pull but only after u fix the jetting issues.......just my 2 cents worth

Right. I knew the motor changed at one time and had heard the earlier motor was better. Well acording to some people 
So the 02 motor is the same as 07 ?

Pretty close yes they added a Throttle Position Sensor to the carb in 04 to 07 different reeds and and some porting differences from year to year but yes there all pretty much the same 02-07.......Ck this link out it gives all the specs on the CR-250's from 1998 to 2006

Holy balls, them's some thorough answers right there.  All I ever heard was the 01 was awesome and the 02 pulled big numbers but lacked real grunt.  But it would appear, and as always, that things are not as simple as they first seem.
