200x vs ATC 185 race

[HondaCT90]

I'm going to race my buddys 200x with my 185 and I'm wondering what one will be faster. The race is just for the heck of it and I know there are a few differences between the two bikes. It's going to be a drag race on flat ground. I would think that both bikes would have a similar top speed, but the 200x would get there faster.

My 185 has a DG exhaust on it other then that it is stock.

The 200x is all stock and I know when he built the engine he did not lap the valves.

My money is on the 200x.

I'd probably put a good sum of money on the 200x. I think the overall gearing on the 185 is lower so maybe it holds its own on the holeshot but then flattens out. Good luck. Regardless of who wins you should swap bikes and do it again. See if it was rider or ride.

200x all the way. That's like racing a sports car against my truck.

200x will walk all over it. Real clutch! Smaller tires and better gearing. It'll get the holeshot and walk away from it the hole race if you guys are anywhere close to similar skill level

I think this is your only chance of beating the 200x.

A 200X SHOULD win every time, but...
I bought a 185s new in 1982. It eventually ended up with full suspension and a Bill's pipe to clear it but otherwise stock engine & carb. I ran the old Nankang knobbies - shorter and stiffer than the stock Ohtsus because I like the way they handled better.
That S always ran strong, even when stock. Like it was put together with all the tolerances on the good end of the spec. Always stronger than my best friend's 81.
It would beat stock 200Xs consistently. Not "walk" them but it would stay in front of them.
I do think it was the exception to the rule. Maybe the Xs we had were on the other end of the spec?
I know that Bill's pipe helped and it should not have done what it did.
That was a great trike.

Even when "stock", the 185's do wake up A LOT with just a good flowing intake and exhaust.

I guess I'll wait and see what happens I was thinking the 200x would win hands down, but both bikes have similar top speed.

[350for350]

Granted, it's a 1980, the first year, but my 185 is geared WAY lower than my 200x was. Maybe yours is geared up? What kind of race are you talking? Drag race on distance?

[HondaCT90]

I think the gearing is lower then the 200x. I don't know what kind of race we will do, mabe try a few different ones out.

[350for350]

Well now we all want to know what happens.

When is the big day?

[HondaCT90]

I'm not going to leave you guys in the dark on what happens. I haven't had time to fix the carb issue on the 185 yet. The fuel/air mix is way off. The new mikuni carb is causing me more issues then its worth.

[350for350]

I know. Put the Mikuni on the 200x and use that carb on your 185. Absolutely guaranteed to win!

When I was about 15-16 yrs old we had a 185s and my uncle had a 200x. They were both only a few years old and were in a good state of maintenance. I think that the 200x was stock, and our 185s had a K&N and a Supertrapp. I weighed about 155 lbs, and my uncle was about 190 lbs. From what I recall, it was close, but he could just edge me in a drag race. As far as top speed is concerned, I can clearly recall one time when we were out on dirt roads with miles of open road and I rolled on the throttle in 5th, and he pinned it also. It was dead even at top speed, and I mean stalemate. Then I tucked down and put my left arm behind my back and pulled my knees in tight and just started to inch away from him. He replicated my position and then we were even again, but I held the number of Feet I had gained by aerodynamic advantage and he couldn't close on me.

However, when I rode his 200x, and it didn't have to carry around the extra 35 lbs, it felt noticeably quicker than our 185s when running up through the gears. So all other factors being equal, the 200x should have a clear edge.
