    Sweet berg. I think most are running skinnier than 3.5 on the 19s, don't know. The narrow rims are tougher?

    I made one out of a 2.15 x 19 rear MX rim:

    Great looking DR, in much nicer condition than mine. WHeels look good on the bike


    @ dentvet
    I really like the Ninja / Versys 650 DS build. Would even consider doing one myself, but just too much work for me. Besides, i don't have a garage/ spare money/ spare time to build one. But would be a great bike.

    @ Idle
    Nice Husaberg.

    For a 19" front wheel you indeed go with either a 2,15 or 2,50 or 2,75 wide rim.
    Then you can mount a 100/90-19 or 110/80-19 tire. Plenty of dual-sport or even knobby tires.

    For off-road you would go for a slightly narrower rim, so the rim is protected from inpact by the tire.

    You could also use more rain type tires on the current rims for better off-road bite, for instance:
    Heidenau K73
    Goldspeed rains
    Dunlop Sportmax Mutant
    Avon Rain Extreme
    Avon Distanzia
    etc.
    SM wheels can work very well off-road. I went off-roading with a friend with a TT-R 600 with SM wheels and his bike was even more stable in loose sand then my DR 650 with the 21/17 Heidenau K60 Scouts!? As long as there is no mud and you don't have to brake to hard, sports-tires work very well.

    You can keep the stock rear rim, use tires as above and lace up a 19" rim for the front for off-roading with an aggresive dual-sport tire. And keep a stock front for the sport tires. Selling the spare hub you have could be a start to a new front wheel. There are so many options. Or try and get a spare set of 21/18 tires from another Husaberg?

    For me next time i will absolutely keep the standard set of 21/18 wheels with knobbies for enduro riding.
    And get a second set of 19/17 wider rims with dual-purpose tires for everything else

    Been there, done that. I started with distanzias front and rear. In the middle of my second rear 160/60, I ditched the front and got an Avon pro extreme rain front. What a great tire, rarely ever stepped out, off road and had great grip on pavement. I got 4,000 miles out of it and it still had some tread on the side. I gave it to a friend. I have a new one in my living room I'm saving for a rainy day.

    The Avon rain is discontinued, they quit making it about a year ago. None are available in the states. They may be availible in Europe, but will be tough to find soon. The rear in the pic is a 160/60-17 Heidenau K73. It never felt right in fast corners and turn-in was weird. It had an abrupt transition, almost square feeling.

    This is with 5psi, I ran it around my neighborhood to try and get it broke in.

    [​IMG]

    It's a really heavy, stiff tire. It worked great in the dirt and i rode a good amount of trails with it.
    The weird turn in was from two things IMO. It's mounted width on my 5" rim at 25psi was 157 mm. It had an abrupt profile, it may have worked better on a 4.25" rim.

    The otter reason was maybe due to mis-matched tire type. Bias-ply K73 rear and the radial Avon rain front. It had great grip on pavement but I only felt comfortable pushing it on slower tight roads. It was $140 vs $200 for the distanzia in a 160.

    Thanks for clearing up the 19" rim sizes for me. I'll check into that.

    hi, its a shinko 244 dualsport tire in a 4.60x18. they are made to run on front or rear and in any direction. many sizes to choose from and are super cheap in price. they are the longest lasting knobby type tire i have used too.

    I liked the Heidenau K73 also. The front was fine, the rear indeed had a slight strange shape. Flat in the middle and very steep at the sides. Never really got to the edge of the rear tire (chickenstrips). Never had any handling problems, but they did spit me off the bike once, at very slow speed with a damp road, a little bit too much lean angle and a bit too much throttle (and perhaps the white paint on the road also helped).

    I never got to try them an a Supermoto though.

    They did get me up here though:

    I guess there are a few examples here that 21/18 is'nt neccesary to have a great off-road machine. I guess 18"front and back works also. Of evne 19" front and back. Or 17"s

    I wish i could get Kenda or Shinko in my country through my normal internet tire place. Really would liek to try some of them.

    Greets,

    I'm thinking of two sets of wheels for my XL500R;-
    Roadwork - 19" front with K70 / 17" rear ME880
    Dirtwork - 21" D606 front / 18" D606 rear
    Still thinking of how to set up this bike, W/E dirtwork / work commuter?

    I went with a 2.15" x19" front wheel on my DR650. I am currently using a Metzler Karoo 2 in a 110/80x19 front size. With one inch lowering links on the rear it had a reduced castor effect on steering and the street biased tread pattern combined to cause the front tire to oscillate from side to side when traveling on soft sand/gravel over hardpack.
    I lowered the fork tubes in the tripple clamp approximatley 1/2", which helped straightline stability and left the flickability very quick on firm surfaces. Felt good in the corners on tarmac and stable on firm dirt roads. There was still some instability on looser dirt surfaces.
    I then went to 1& 1/2" lowering links. It now is quite stable on sand, gravel and loose off road surfaces. On street it is not as flickable but has good straight line stability and is stable in corners. I can change line mid corner.
    One thing I have noticed is that there is more stability with wider rims. A 2.5' is more stable than this 2.15 and a 3.5" rear rim is more stable than a 2.5" on the rear.
    Recently purchased a new to us 110/80x19 Pirelli Scorpion Rally front tire. It is over 1" taller than the Karoo 2, although it also has the lower FIM size knobs. When it is installed l should be able to return the fork tubes to their normal position.
    Would like to hear from anyone with more geometry knowledge on the effects of changing the fore/aft pitch of the bikes when changing sizes and the effect of tire width on traversing soft or mixed terrain.
    Even the vintage motocross racers go to 21" front tires on their 500s and 650 sleds, while we are in effect going the opposite way with our wide 19s. I do notice on this bike that it may float on top to a degree but find it better than tlhe narrow 21s digging in. Alternate views? Thanks, Tom

    By lacing a smaller wheel in diameter in front, you effectively reduce trail which affects stability. The more trail the more stable. Also the more the trail is, the more effortless countersteering becomes. Steering angle also changes (if you don't compensate on the back) but the main effect is on trail.

    Hi,
    I'm approaching the 19-inch-question from the other direction. Iris, my lady, rides a Suzuki GN 400 since 1981 (from new). During the years we have aquired more than one more of these ...
    Iris got a 1972 Triumph Bonneville, too. In the early 90's. It became obviously that the term 'basket-case' wasn't really describing it's state. We're still hunting for parts for it ...
    Some weeks ago I planned a dual-sport-ride with a friend of our's with my Suzuki DR 750 Big. Because of a crankcase-bearing-failure of my Big, the whole affair didn't take place. But that's another story ...
    While preparing for the ride (getting me an off-road-helmet with goggles, boots, trousers, shirt and armour) Iris dropped the note 'I'd like to join you on this ride ...' Something I never would have expected.
    I ride one of these many GN 400 in our barn, too. Equipped with a broader and flatter super-bike-bar and a pair of old BMW-GS-footrests. I've always been thinking about converting it to a 17-inch rear-wheel to get me a proper, grippy rear-tire. Now I'm thinking about changing it's front-wheel to 19 inch to be able to get some mild off-road-rubber (Heidenau Scout) on the bike and thus transform it into a scrambler. Just to give Iris a chance to join us on dry days for some green-laning. Because I know, that she won't ride a bike that doesn't enable her to get at least one foot firmly to the ground. The GN does! And with a 90/90-19 up front and a 120 or 130/80-17 on the rear (3.60-18 and 4.60-16 original) the bike won't rise too much!
    So I'm very interested in this discussion, especially concerning a front-rim that fits the original GN-hub (been thinking about the Freewind-rim myself). On the rear, the rim of a drum-braked Big will do - even with the Bigs original spokes as it seems! And, what's been new to me, that a wider off-road-tire up front would provide more grip on the road?
    Kind regards, Bambi

    Got another thread (http://advrider.com/forums/showthread.php?t=850683) where got some input on tyre choice but not really wheel size.

    These are my options:

    - 21"/18" wheels (OE KTM 690EnduroR)
    - 17"/17" wheels (690SMC wheels)

    Planning 5000km/3000mi trip this summer, probably a little bit more tarmac than gravel. But will be good gravel roads and mostly not that twisty. So no mud, sand or rocky stuff at all, hard packed gravel mostly.


    So question is, will 17" front be OK? Must admit slightly nervous on tarmac on 17"/17" even though got SMC forks/shock so correct height. Nothing I mind and got steering damper anyway but maybe more of an issue on gravel?

    Could of course buy a 19" front wheel but prefer avoiding the expense...

    Never mind, got a hub and found a 19" rim on internet so then I'll go for the adventure wheel conversion myself, thanks for the idea, never thought of that option before saw this thread!

    I'm curious about which rim widths to go with and possible tire recommendations since I won't be tubeless. I'm thinking I'll probably go 150/70-17 in the rear and 110/80-19 in the front, some wet roads and gravel, but really, these'll be my street/touring/hooligan wheels/tires.

    I got traded my SM wheels for some dirt wheels a couple years ago and then lowered the suspension via a lowering link and dropped the front as much as possible. I'd like to go to the 17/19 combo mostly so I can restore the suspension to how it ought to be while still being able to stop without falling over.
