    Well I finally got to test ride my new 19/17 setup and all I can say is WOW!

    [​IMG]

    I ran a 380 mile test loop on some of Colorado's best roads.

    My goal for this set up is to have a pure street kit, so I can swap between my dirt wheels (21/18 - D606/D908), which I run most of the time; and a pure street set-up (19/17 - Conti Trai Attack F & R) for the occasional road blast and for winter riding/commuting when the hills are snowed in.

    I love the way the bike handles. The 950 in standard form is great and handles well, but the 19/17 really transform the bike. There is a reason why all the street oriented DS bikes use this set up: it simply works!

    The stability and hook up in the corners reminds me of my old Kawasaki ZX-6. I spooned on a set of the new Conti Trail Attack and could not be happier. I used to be a big fan of Anakees when I had my GS, by I must say I think these are better, certainly stickier. How well they hold up and how long they wear is yet to be seen, but in the traction department they are certainly better.

    I went with silver rims because I spoon on my own tires and don't want to be bothered by having to be careful not to scuff up fancy color anodized rims. Second because I got a good deal on a used rear rim from Woody's Wheel Works where I had the wheels built. I got a good deal on line on a used OEM wheel set and just had it re-sized and super laced by Woody. Of course I went with tubes, cause everyone knows that tubeless on regular spoked wheels is experimental and only good for short intervals.

    I actually like the 19/17 set-up better than the 17/17 I had on my supermoto, it's less nervous and twitchy. I do not have a steering damper, but the bike is very stable at all speeds, to include top speed runs and hard decelerations and accelerations. In the corners the extra meat up front really lets you drive the bike through the corners like it's on rails.

    For gearing I decided to run 17T-42T for the 19/17 set-up & 17T-45T for the dirt wheels, This allows me to keep a 17T up front which is more chain wear friendly and drop down to a 16T-45T for some extreme dirt and single track; all without having to change the chain.

    I got to make a couple of runs up and down Independence Pass without any cars in sight. This was the last day the pass was open for the season. What a blast this road is:

    Well, I just can't take the shit eating grin off my face. The 19/17 set-up on the 950 is that much fun.

    PS Sorry for the immage size

    Dan- does the smaller rear wheel affect the speed of the bike any? I have a 17 / 17 combo that I haven't even tried yet. I'm gonna run 16 T / 42T when I get it on the road.

    Not really since I'm running 17T-42T for Street & 17T (16t)-45T for Dirt. This keeps the speed and gearing ratios the same for different wheel sizes.

    16T-42T might be a bit too short for a 17/17 set up. Would be great for racing on a go cart track, but I think it will be too buzy for road use.

    I'll be curious to see how th 17/17 feels? Wonder if it will be as twitchy as they say?

    One thing I forgot to mention is that it makes the sidestand difficult to use. With 19/17 or 17/17 the sidestand becomes too long.

    Fehh! I ditched the side stand for a centerstand. Good to know, though.:thumb

    I've been running a 17/19" set up but with Avon Distanzia tyres for about 3 month (when work allows) and all I can say is 'WOW!'

    The turn in is sharper, the stabillity stronger, the drive out of corners is 'deeper', I can even touch the floor at junctions!:rofl

    The side stand is not an issue on UK '03 spec bike, but I took off the wide disc which I see is still on your side stand foot. I have heard '03/04 bikes were taller though...

    Really pleased with the new set up (if not the bank balance):clap :clap

    17/19 rocks.

    I've had mine with Distanzia's for about 6 months. It works very, very well. (Even for occasional off-raod use when I'm too lazy to change wheels, or when we somehow wind-up doing un-planned off-road).

    Looks purdy good there Dan. Hey, I got an old pair of snow ski's if ya wanna mount 'em up front.:huh
    Looks like winter's settin in on ya. I'll bet that 17/19 combo hooks up a lot better when the roads warm up next summer. ---Mark---

    I have a new 990 Adv and would love to have two sets of rims. Has anyone tried the 19/17 set up on the 990 Adv with ABS? I would love to have an extra set of rims with for the street and knobs for the dirty stuff. And as long as we are on the subject of street biased equip... what about brakes? Anyone switched to a stronger brake pad such as the EBC? I feel like the brakes could use just a bit more oomph in the stopping dept. What I really want is a Super Enduro with brakes off the Super Duke. Not very realistic but sometimes it would be nice.

    I had no isses with braking power. The seat of my pants dyno tells me there is more braking power w/ the 19 than w/ the 21. If you think about it, it makes logical sense:

    1- Larger contact patch w/ the asphalt.
    2- Since the wheel diameter is smaller there is less leverage force on the brakes.

    Imagine the axle as the fulcrum, the brake (B) as the effort and the tire/asphalt contact point [where the red hand is (A)] the load.

    Also known as a second class lever.



    [​IMG]


    The greater the distance between A & B the greater the load, which means more effort is required

    Not sure if this will make sense to many people. Oh well!

    Regarding the ABS I'm not sure what the results would be since I assume the ABS is calibrated for a set wheel diameter and stopping resistance, then again it might just sense wheel lock-up and let up on the brakes?!?!

    :thumb Yeah, I got Woody's 19/17 on my 07 SE also. Fantastic setup. I would recommend to anyone who wants the best of both worlds.:D

    Hey Dan,

    I'm curious if you're using stock rims for the dirt set-up.

    I just wonder because I know you like the gnarly stuff,and the stock rims are so weak that I'd be a little surprised at you having a street set made before having a dirt set made....

    As cool as the 19-17 combo is, I think a strong off road set is a higher priority for me. Riding through sagebrush with hidden rocks in the middle of nowhere this summer had me scared to death with visions of being stranded due to a wrecked wheel.

    This combination IMO cannot work on dirt. The new 1150 adv will be more road biased and will use this combination.

    TUBELESS ISSUE:

    I could care less about the tubeless set up, don't really get what all the fuss is about. On a long remote trip it's easier to just carry extra tubes and some patches and be done w/ it. I once had a brand new Anakee get slashed by a rock at high speed right through the meaty part of a knob in the middle of butt f@#$ Colorado on a Sunday. Had to make an emergency repair with 10 plugs, chewing gum etc... and re inflate my rear tire every 4 mile to get home (60 miles away).

    If you are a street only rider it is easier to plug a nail hole than change a tube, but the advantage only applies to this single scenario.

    21/18 vs. 19/17:

    I disagree with you. I rode the bike with 21/18 and the stock Pirelli's just before the switch and I found a world of difference in handling and hook-up especially when hauling ass and pushing the limit. For performance riding there is no comparison.

    Having said that if I were to only have one set of wheels I'd have to stick with the 21/18 because they can do more.

    I got my second set strictly for street and performance riding w/ no intention of using them on anything but asphalt.

    Later Dan


    PS: I've still got the OEM Pirelli with less than 400 miles on them if anyone is interested?!?

    Hi Saul,

    What I did was take my old dented and thrashed wheels and had them converted to 19/17 purely for street use.

    I kept the better set for the dirt. The rear rim is a tad more narrow 4.0 vs. 4.25 and works well. Once I destroy the front I will get it rebuilt. I figure I'll use the street setup more in the winter.

    By the way I'm closer to getting a new front rim than you think. I made the mistake of taking the new to me 21" wheel out for a ride up Rampart w/ a front TKC @ 32 psi and dented the shit out of the rim on stuff that a D606 @ 25 psi would have not even felt. The TKCs in my opinion have too soft a side wall.

    I went to a 19" front while keeping the 18" rear - - - no problems at all.
    I was all the way to sidewall on my 21" Roadrider - - - wanted more sidewall (see comparison below):

    I have two sets of 18" rear OEM wheels (4.0" & 4.25") - - - may consider selling one to get a 17" rear. What is the reason KTM went from a 4.00" in '04 to 4.25" in '05 and later? I have a 150 Roadrider on the 4.00" and it works great. More tire choices if I get a 4.25" X 17" rear.
