Atc110 vs. Trimoto125

[snapon14]

I have both an atc110 and a trimoto in my possesion currently. Obviously the 2 stroke is alot quicker but it has seen far better days in everyother aspect. Is there any chance of building the 110 to compete with the trimoto? I was thinking along the lines of getting a cam, carb, porting the intake/head, and exhaust.

Parts can be a bit hard to find but that 110 can be built up to be pretty quick . What year 110 do you have ?

Its an 84 and I should mentino that I have no intentions of racing it. Just having some fun trail riding.

Well, if you are going to build the 110, then you may as compare that to putting a yt175 top end on the yt125. And if you are camming the 110 and such, you may as well make that an it175 top end with the better porting and just go ahead and polish up your ports as well. I mean, let's keep the build up a little even instead of a tricked out 110 vs a stock yt125. And if you are going to swap front ends, then lets talk the yt175 front end on the yt125. May not be quite as much travel as an aftermarket 110 front end, but better than no front suspension.

I think what you are saying is that it isn't extremly hard to build the 110 to keep up with a stock yt125 but for the same price I could build up the yt125 to produce even more power than the tricked out 110. If this is true I'm going to go on with building the 110.

I don't know about more power, but they can be pretty even unless you are running super high compression alcohol engined atc110. There are good and bad points to both trikes. The yt125 has a sturdier frame stock. To get a sturdier frame for a 110, you have to buy a used aftermarket frame. You can have rear suspension for both machines. If you find the yt125/175 rear suspension kit, it's a matter of drilling 2 holes bigger and grinding off a couple parts and bolting on your kit and you have rear suspension. For a honda to have rear suspension, you have to buy a whole suspension frame, but I know where there is one for sale right now. The yamaha engine sits farther back in the frame and it's a wheelie machine compared to a 110, but the yt175 front end helps that. Parts for both trikes are getting harder to find. To get the 110 to 185ccs, you have to split the cases and find a stroker crank. To get 175ccs from the yamaha, you just have to bolt the top end of a yt175 on it, but you need the carb and the fuel pump and the yt175 fuel tanks help as well. There are no maier plastics for the yamaha yts', but there is maier plastic for the 110. Both trikes use the same rear wheel spacers, 3x100 bolt pattern. So it just really depends on where your tastes lie. I have a suspension kitted yt175 that I'm working on slowly. I also have a suspension 110 frame and quite a stash of 90 hi performance parts. If you like 4 stroke, then honda, if you like 2 stroke than yamaha. Either built up is very cool. I could show you some pictures of a board members tricked out yt175 that you would flip out over. Douglas wheels, all aluminum or most of it anyways, polished. A trick aftermarket front end, the whole works. It was a copy of trike magazine project bike and it turned out super nice. It just depends on how crazy you want to get. It's alot cheaper to find a used yt175 top end and get a new piston than it is to stroke and bore and find all the parts for the 110 mods, I can tell you that. Heck, you can even get your crank rebuilt and all new bearings and gaskets and seals and be way ahead price wise on the engine mods. You can even make both trikes manual shift clutch if you want and you could make both kickstart, no problem either. It's just a matter of mixing and matching some parts. But for kick start, you have to remove the rear fenders of both machines to kick start them, as opposed to leaving them pull start, but it's a matter of preference. So each trike has alot of options. Pick your poison. LOL

Well it seems as though I'm going to build the 110. I don't think that it is going to be extreem enough for any stroker or aftermarket frame. I was wondering if there are any easy swaps I can do to get rid of the bulky front tire without changing the forks. I think that I want to stay rigid.

I don't remember if the front axle diameters are the same or not between the wide stock front tire and the 200x,250r or 350x, but....if the axles are the same diameter, then all you would have to do is just make spacers for each side of the axle between the forks. If the axles aren't the same diameter, then you may be able to get away with finding bearings that have the stock outside diameter as the new hub, but then you would have to find the inside diameter of the old hub, do you understand what I'm saying?
