    I am about to order a Sun Rim to replace the one that I dented real good on a high speed desert G-out, I didn't even hit a rock, just front wheel landed, the excels must be made with extra butter alloy, it must do wonders for replacement sales.
    I tried to do a search but the engine doesn't take 3 letter keywords
    has anyone run a 1.85 instead of the stock 2.15 ?,
    is it less likely to dent ?
    does it affect handling ?
    I wonder what a 1.60 would be like, I happen to have one of those in stock

    I think I just found the answer to my own question, I noticed the SE uses a 1.85 Dirtstar DID but it's $285 from KTM
    Anyone have an idea where I can find another source for a DID dirt Star ?

    I found out I can get the dirt star from ktm for $215
    or the Sun from buchanans for $195 + 35 for black so $ 230

    It looks like the SE rim is winning so far as long as the hubs are the same

    How are the SE rims holding up ?

    Ignoring how much money you are trying to save on the rim...
    There are a world of rims, hubs, spokes, etc,..
    Yes, a bulletproof setup can constructed if you choose wisely.

    For example, look at Woody's website for reference.

    Your issue has everything to do with how much you are on the trail vs street.
    Only you can answer that question.

    I don't know the answers to your questions, but I thought that the sun rims were the strongest out there. Woody has a thread over in the vendors section. I think he'd have a good answer.

    Oh I forgot to mention. Check out the rim pins available for the suns. They look pretty cool.

    I've bent the rest so now I have gone with the best!

    If you ride a lot off-road, and ride it hard, there is only one rim to have.

    The 1.6" x 21" X60 by Excel.

    This is by far the strongest rim of all, the downside is, smaller contact patch if you plan on doing much road work due to it's narrow width. This rim is 20% stronger than other 1.6" rims and I reckon 50% stronger than 1.85" rims. Stronger section so you don't get the usual bending.

    Had Woodies build one for me a year ago and it's the first rim to make a whole season on the 950 w.o. a ding .:evil
    To be fair this was the first summer with a Superplush revalve / spring and S spec fork and softer rear spring (that combo surely takes some load off the front rim ):ricky
    I like how the smaller rim handles on the tarmac better as well . With a 606 front , 908 front was my least fav. on and off .
    908 are the bomb on the rear IMHO ! Later ...
    Update 2 / 16 / 2010
    another year and still going strong , A60 rocks !!

    FWIW, I believe the A60 comes only in Japanese indexing, so with the stock hub you'll wind up with one side 2 cross and one side 3 cross. Woody built my SE wheel this way and it's been flawless for a season now.

    Thanks to Hanuka Harry and Woody's Wheel Works, I just got my 1.6 Excel A60 on last week. Only have a couple of rides on it so far...

    I mounted an MT-21 front at the same time to go with the 908 rear. I've never run the MT-21 before, so I don't know how much of what I'm feeling is the tire and how much is the rim. I can say that the bike feels way more planted off road than it ever had before (likely the tire, the MT-21 grabs dirt better than a TKC80). On road, it also feels great. It turns in much better than it did before, and grips just fine for street-speed corner carving. I was concerned about going with the narrow rim since I like to rail the twistys, but those concerns are gone now that I've tried it.

    Looks burly too, I was really worried about the stock rim leaving me stranded in the middle of nowhere, I'm glad to have that worry out of the way.

    :thumb to Woody's as well. I dropped off my bent-up wheel, and they had the new one ready for me in less than 24 hours on the week of Christmas! Now that's service.

    Oh yeah, addressing the O.P.'s questions..

    Yes, the 1.85 is less likely to dent than a 2.15. As for affecting handling, most that have gone to the 1.85 report that they can't tell the difference.

    I read everything I could on this and found that even though the 1.85 were less likely to bend, they still do bend pretty regularly. I've seen no such reports on the A60's, so that's what I went with. I'm glad that I did.

    The A60 was also about $20 cheaper than the Sun 1.85!

    Yeah I got the Rad hubs on mine with Jap indexing which allowed me to have 3 cross on both sides. Strength wise, probably not much difference, the weakest link always seems to be the rim!

    A60 = :thumb

    After crushing the 2.15 stock rim, I had Woodys superlace an Excel 1.85, HD SS spokes, and anodized orange RAD hub for dual brakes. If memory is correct, the rim was $250?
    For me,... the difference riding on the street was insignificant.
    But the farkle/performance factor was 200%.
    Saving for the rear wheel build.

    Great info everyone :thumb

    Thank You All !

    I have heard that the new DID Dirtstar is on par with the A60
    I believe the A60 is only available in 1.60 ?
    the stock SE dirtstar rim comes drilled for the same cross pattern and is 1.85
    but 1.60 might be better


    FWIW, I was running a MT21 at 22 psi and picked up two dings and a big bend pretty quick

    I'm running an A60 on the front of one of my RFS bikes and it's proven to be very, very tough. Tougher than the Suns I've used in the past. It's the hoop that survives Baja.

    Too bad the rears only come in 19".

    Have any of you running a 1.6 x 21 front rim experienced many pinch flats?


    curious.

    I had Woody's build me a set of Sun rims for my SE. The front lasted all of 12 miles. I've been running Excel's ever since and they've never failed to get me home.
