Top Speed??

[TRXRIDER4567]

I have no prior experience with any 250r and was wondering what is an average top speed of a completely stock one?

[Aceman]

Top speed?

28 mph. Yes, twenty-eight miles per hour. Barely faster than a 6-year-olds powerwheels if you ask me....;)

[bansheeboyo]

are you kidding me 28 mph

[bansheeboyo]

the 31 srwhp will make the 250r do 71mph

[TRXRIDER4567]

so a stock 250r will do about 70?

[TRXRIDER4567]

ok thanks , i dont get why people have to be smart a**es though

[mineralgrey01gt]

whoa if thats right for the tri-z, im going to get me one asap. That would be a killer ride on 3 wheels

[bansheeboyo]

the tri z must be pretty right ive been to many forums and they all say 68 and also i had this list written down off a old off road magazine i just took the triz asa spelling error in the mag
who knows

[atvmxr]

if the tri-z had 68, then its an absolute shame they never made a 250 quadracer to compete with the others back in the 80s.


take that zilla motor and put it in a 250R and you have yourself nice lil scooter ;)

Because you're too lazy to do a search, that's why. A 15 sec. search and you would of had your answer, but no, let's take the same amount of time and start another thread about it. And then wait for replies. I just don't get it.....

I don't think so either... I started on trikes back then, my first being an ATC250R and I don't remember the tri-z being anything to shout home about. They had a longer wheel base, and were supposedly "safer" but I don't remember hearing they were hp monsters.

Where did you find the info? I'll do a little research too, I've got some old magazines from the 80's. If that is the case, a stretched blaster with better suspension, brakes and a host of other things would have been killer with a tri-z 250 motor.

[troybilt]

BTW, You need to add the Tiger 500 3-wlr to the list... that thing was ridiculous...

[mcboomport]

I highly doubt the Tri-Z had peak hp in the 60s. My dad raced 250r and tri-z trikes in the 80's. He got sponsered by a local yamaha shop and was given a tri-z. He told me the 250r was a bit quicker of a bike. He said he still kicked some ***** with the tri-z though. He also did say that someone came to the races once with a Tiger. He said nothing could touch that bike, he was amazed by that thing.

[bansheeboyo]

know wonder no one could touch the tiger it only weighed 280 lbs and had 45 hp stock
yes i also doubt a tri-z had 60 + hp peak i was thinkin more like 28 or somethin

[2muchquad]

I have personally ridden a tri z and it was a fast bike but i think hp in the mid 30 range would be about right.The 86 was(still is) more desirable than the 85 because of its 6sp tranny.;)

[deathman53]

tiger made several models, 80, 125, 200, 250 and 500. They tended to race the 200 in the 250 events, so you probably didn't even race against a true 250. I have an article with the 500, dirtwheels said it could go 90+, and its geared kinda low, so 1-2 teeth on the front sprocket is easily pulled. Each tiger atc was a custom order, there wasn't a standard model, everyone was built to the customers spec.
