wich would have more power, a trx250r, with pipes and stuff, or a stock ltz z400. the 250 would have more power right? and the 400 would have beter low end tourque?. plse, i need help, thanks

there's a reason 250r's were used until gncc rules prevented it

so this means? 250rs are faster?

This may be a little off topic..I have never ridden a 250r but I have had a z..the z has tons of bottom end power but I believe it is a little deceiving because the front end is so light..just my personal preference but you can't beat a 450..I have ran across many great deals on 450s..not only are they stronger the suspension doesn't even compare..I would honestly take a stock yfz450 over a totally modded race ready z.
