Xt350 Vs Xt225
Posted 06 March 2009 - 11:29 PM
I am leaning toward the XT225, as I have seen there are many more aftermarket options than with the XT350. The added displacement of the 350is nice but with the age of the bike, is it really going to be that much of a difference over the XT225. I think with the exhaust i have checked into , rejetting the carb, and the gearing change the 225 should be close in range to the 350, but I could be wrong. I will also have cash to get an aftermaket exhaust, rear sprocket, and re jet the carb the 350 so again that should give more power.
I am not at all familiar with Yamahas:excuseme: so those of you who are your input would be realy appreciated. One other thing to consider is that I have seen some killer SM xt225's and am thinking hard about making the 225 a SM if I decide to get it.
****The over bore on the top end was .040 with a Wiesco piston, the heads were re-worked and the jug not replaced but bored out. Does any one know what that changes the displacement to?****

Dual carbs on the ol' thumpers aren't really an issue. Only thing that's a PITA is when ya have to remove it. As for starting, my 550 starts easily. All it takes is technique, and once you master it, it's a piece of cake. Regarding the displacement, you could calculate it. A stock XT350 is 86 x 59.6 (bore x stroke). 3.14 x 43^2 * 59.6 gives you a displacement of 346.02CC's. 0.40 is 1mm overbore so that would make it 3.14 x 44^2 * 59.6 = 362.31CC's. Anyone please correct me if I'm mistaken
Thanks for the info on the displacement, as for starting the big thumpers, I have a XR600r that I can usually get it to fire within 1-2 kicks. So the kick start doesn't really bother me, I am just getting lazy, the KLR electric start is so easy to fire cold or warm, one push of the button and it is ready for action.
I really like the bigger displacement bikes and the 350 is really closer to what I am looking for size wise, but a well cared for newer bike is really a great enticement. I talked to the guy who has the XT225 and I am going to take it on about a 20 mil round trip on one of our local two lane Highways. If I can get it to maintain 60-65 without feeling like I am running it to death I just may go with that one. I usually only run 65-70 on my KLR on the freeways anyway so its not like I am going to be missing out on speed that I just don't use much. When I want to go really fast I usually take the XR600 and really get on it. With al the performance mods on that bike it is a very fast bike, really too fast:busted: , but very, very fun!

The XT350 would be better on the highway IMHO but the 225 could be made more streetworthy with different carbs, gearing, etc. Good luck. Wabbit

As others have said, both bikes are stone reliable, with a nod to the 225 for ease of maintainance. There are some cheap mods that will perk up the 225.

I am going to look at the XT350 this week but I have a feeling that it is going to be the same thing, but I will wait and see.
I am beginning to think that I would be better off getting a DR650, it is lighter than the KLR but has the power and size to go anywhere I want to go. I am also strongly considering the DR400, it has much power and is big enough to ride two up, but is small enough to quickly load up and go, and for me it is water cooled a big plus here in the Central Valley.
Thanks for your input, but I think I am not wanting to go as small as I first thought.

I've owned both the XT-350 and XT-225.
I also read somewhere that it has a dual carb set-up, that to me is a definate minus, I like a single carb set-up on a single thumper.
I read this sometime, too, and all I have to say about it is that every Yamaha thumper with the YDIS (dual-carbs) I've owned (three of them) worked fine with no trouble.
My guess is the trouble starts when they get messed with.
A classic scenario is a bike being brought back into use after sitting for years, the carbs having to be taken apart, and ever since that point the bike won't run right.

Actually, the XT-225 has the older engine design of the two:
The XT-225 is based on the 1981 SR-185 street thumper, and the XT-350 engine is from the 1983 XT-250 that was first sold in Japan, which was brought into the USA in 1984.
The next year (1985), it was made into the XT-350.
If you were to ride the two bikes back-to-back, the XT-350 would feel like it has twice the power of the XT-225.
Simply more power and torque at all RPM.
Of course, the XT-225 is smaller and lighter, but not 50 lbs. lighter - more like 28 pounds (238lbs vs. 265lbs, if I recall).
Basically, to me, I really liked both bikes, and it comes down to the classic case of power vs. size and weight.
If you want a small and manoverable trail bike that's also street legal, go with the XT-225.
It will never be a rocket ship, but it gets you where you want to go quickly enough.
If you want a full-sized dual-purpose bike, the XT-350 is a good compromise because it's got more power without a massive increase in weight.
It's 265lb dry weight is actually one of the lightest Japanese dual-purpose bikes made, past or present.

I didn't weigh mine, myself, but the claimed 265lbs. felt accurate.
I know about the TT-350 from a close riding buddy back in the day who rode with me for many miles on one.
