Most minis will do about 30 mph with all of the restrictors removed.

Our stock TRX90 with an eighty pound rider tops out at 34MPH. That's clocked with a regular speedo so it could be a couple of MPH slower, give or take. Our stock LT80 is just slightly faster on take off with a little less top end.

Yeah, pretty fast for the crappy cable brakes, and adult reach levers and worthless suspension the manufactures's put on a lot of the mini's. Not all have bad brakes, some have rear disc's.

thats cool then if a modified 90 can do 50 then why can a z250 and 250 ex only do 54

The answer to that would be: rpm's and gearing. The stock LT runs about 6500rpm's. My moded LT's run 9800rpm's
I'm guessing that the machines you listed run about 8-9000rpm's The bigger motor allows for the gearing difference for the extra speed.
