Accurate Top End Speeds of ATC's

[InPiEcEs]

Ha....Maybe I shoulda posted the link here instead of this vs. that last nite.....LOL
I didn't think it would be such a hit
For what it's worth......when my 86 R was still fresh and stock, other than a DG pipe, it would top out in the 70 mph neighborhood on hardpack.

This was on a thread on 3wheeler.org posted by MR. ATC. This should end the mass confusion in earlier posts. Radar and GPS are the only way to accurately measure speed...
"the end all list... TOP SPEED of "my" trike
here is a list of the "aproximate" Average top speed of the majority of the most popular 3Wheeled ATV's. this list is based on severall criteria including magazine articals and test, manufactures "claimed" top speed, ( before lawsuits the manufactures were not afraid to post top speed in there spec sheets), and personall experiance using such equpiment as radar guns, atv mounted factory aproved and tested speedometers, side by side riding with comparable ( i.e. XL on-off road m/c's) by riding on flat paved sufaces on distance's of over two miles. (how fast your buddy, the cops, or whoever had to accelerate to to catch up to you on your trike is not the same).

Those speeds are outrageous...completely false! The 84/85 Tecate tops at 70 in stock form.

[Wi200x]

I was thinking 45 for the 185s and 55 for the 200x.

i had a 78 atc 90 with stock gearing and stock motor go 40mph on the road ( followed by a car) and this was with 18'' tires ....so 48mph seems right on for a 110

[DixiePlowboy]

Anyone still have the '85 200X exhaust shootout article? It was either DW, 3Wheeling or 3&4WA, I can't remember which.

Using a radar gun, they were getting low to mid 50 mph readings. If memory serves me, I believe stock was like 52mph.

[dirt bike dan]

i dunno man the gearing is stock, and it really is top notch it just seems to have a close ratio gearbox, im sure itd pull 75 no prob w different sprockets though!!

If your more than the average rider of #165 most 200x's won't pull past 50.

[rally4x4racer]

if 48 is tops on the 110 - mine is a PIG.
If I let it wind out it MIGHT hit 40.........

[vegas250rr]

call me skeptical, but 55 for a 185s, and 50.1 from a 250sx? If the honda line spedos are correct, my friends 22 year old, non rebuilt, absolute stock, 85 250es, geared lower than the 250sx, does 54-55, flat ground, oem tires. Id like to know how these numbers were achieved, from honda? from hondaline spedos? from the ol "well i was following my buddy in his truck..." radar gun? gps?

I have never trusted bike speedos, but the 50.1 SX speed was mine clocked with GPS at 2200' above sea level....

I have since broken that run at 54.6 (with GPS at 6500') mind you I was on flat ground but the run was nearly 2 miles long and I was speed tucking like a mofo! oh, and I was running 22" tires as seen in the picture below

[whipit]

Those numbers are pie in the sky or the gearing was altered/motors modded. There is no way an old atc110 will go 48

Dirt wheels magazine did a test with a bunch of sport quads almost 20 years ago at the drag strip, they used a radar gun. The only machines that were in the high 70's were the banshee and LT500R. The 250cc two strokes were high 60's low 70ish . They threw in a kawasaki Mojave and I believe it did 54 or 55

That 250sx would probably do 55 with the correct rear tires on it

[crackshot]

Yeah I think those are bogus numbers. My 85 250R is fresh rebuild, stock gearing and stock tire size and its all bottom end. It probably does 55 tops.

Not trying to flame or anything, but there must be something wrong with your R. My '83 200 with stock tires and gearing, topped out at 56 over a 1-1/2 mile paved stretch. I have also personally seen an '82 185 top out at 57, also stock tires and gearing. Both machines were hauling arse with the throttle pinned.

Remember guys - those numbers on that list were obtained on pavement, over a 2 mile stretch, and no mercy to the throttle. They probably blew the motor on some machines getting those numbers too.

We used my unlces older truck back in the day and that thing would top ( the speedo at least) at 85 and my dad's tecate and my R ( before I owned it) were right on him too

[Levithan]

I think the only way to settle this debate is for somebody to test all of the trikes listed with a GPS. I can tell you right now that my friends 200s probably didnt top past 45, so Id think we definitely need either a radar or gps to settle this. Hehe, if youre really interested, take your bike out on the street and find one of those signs that tell you how fast you're going. Just make sure there arent any cops around!
