Anyone here have any idea of how many horsepower a 350X (stock) puts out??? I was thinking that the 250R was 38 or 39, just wondering about comparison.
Thanks

I think the 350X is like 32hp is what I've heard, but I'm really not sure. Even though thats close to the R, the R is lighter. Its the HP to weight ratio thats key, including the rider's weight.

I might add that all of the above is from the owners manual. i.e. directly from Honda.Originally Posted by atc1985

Am I missing something here?
What does "PS" stand for?
I've heard of "Brake Horsepower" for the Brits and "Newton-somethings" in another part of the world but PS?
Hmmm.....PS, A japanese derivative of HP?
Could there be a conversion involved....like going from SAE to NET HP?
Am I thinking too much?

I thought the HP on a 200S is 12? Anyways thats a different thread. I've heard so many different HP ratings for the 350X.
You agree on 27HP then Wickedfinger?

I agree with 27 HP....just curious if the 27PS actually stands for U.S. HP rating?
Not to insult any of the 250R guys....LOVE those trikes!....
BUT isn't 38/39 hp a bit on the high side?
That's a LOT of HP for those old tech motors.

38.8hp to be exact. From what I've dredged up on the net and from mags, the ATC200S only had 10/11 hp, believe it or not, the ATC185s has the same rating but its torque is less. The first generation ATC200Xs have 12hp while the second gen. big valve motor has 14. The ATC70 has 3.5hp, the ATC90's had 7hp, ATC110s 8hp and the first gen, horizontal motored ATC125m 8.5hp. (I do not know what the second gen upright motors rating is). I have never come across ratings for the ATC250ES or BigRed motors. By contrast the TRX250X has 15.6hp and the TRX300EX 17hp.

the early big reds would be the same as the 200s i would imagine, same motor, just different tranny. unless the added friction of the sub tranny would make that much of a difference.

27 HP for a 350X is lower then I expected,I thought the 200S had 12hp?I don't want to hi-jack this thread but I was just wondering how much better a 350x engine works then a 200X engine?( i have never ridden a 350x before)is the difference amazing?(I know that it would be faster 16 hp vs 27hp and 350cc vs 192cc)
