I'm assuming we're talking a TRX250R?
You're talking about how powerful a 250R while comparing it to a stock blaster with a FMF pipe? That's like comparing a Honda CBR600RR to a Yamaha Zuma 125 in their stock formats!
Sure, the 250R is light and nimble and puts out good power. It was built in the late 80's by Honda to compete in a competitive 250cc class.
The blaster was designed using a late 70's dirtbike knockoff engine as a good inexpensive starter quad.
That being said, you really need to compare an "updated" blaster to that 250R to get an actual comparison. I'm not talking a built stroker BBK blaster, but just a ported and head redesigned blaster to that competitively built Honda. Now, I'm not suggesting that anything other than displacement is going to overtake something in the same basic level of tune but you're really comparing apples and oranges now!
