I was just wondering if these two motora were the same?? If not what is so different between the two.
Thanks in advance

 

They are not even close. The TRX version is based on CR technology but of the early 1980s and not the mid 1980s.

The TRX is completly different from the CR engine.

The counter ballancer is the biggest difference between the two along with the transmission and cylinder porting design.

 

a new CR250 puts out a lot more ponnies. but to the eye they look the same (in the 80's)

 

I rode a 2002 CR250 and its not even comparable,if I could afford it,I put the motor in my trx and just try to deal w/ the vibration,cant beleive how much grunt they put out,its a bunch[img]i/expressions/face-icon-small-wink.gif[/img]

 

here's something i saw a long time ago

1992 CR500-~28HP
2002 CR250-~55HP

notice the '02 is a 250, and the '92 is a 500!!!!

 

how many gears does cr have?

 

a CR125 has 6, and a 250, 500 has 5.

 

Rincon depending on the year the cr has 5 i know in 2001 02 and 03 it had 5 gears.

 

ya, now that i think about it, the 125 has 5 gears, thanx.

 

the trx motor did not have a power valve, the new CR motors also have case reed induction. The TRX was old tech even for the 80's the ports were dirty and not well shaped anyone w/ a dremmel tool could do magic, don/t dream of touching you CR ports unless you know 100% what you are doing, the motor was made to have an almost electric feel, no hit just smooth power. It only put ouy like 25 hp or so yes less than a 400ex it was faster b/c it was lighter. Today a CR is close to 40 or 45.
