    I am thinking of having a more road type wheel (easy swap) for my 950. I would like to keep the same wheel in the rear for simplicity. Also I want to have the bike lower so the wife can ride (touch the ground)
    Given tyre selections, is 17 inch the go? I plan to run Scorpion type tyres, possibly K60 Scouts.
    It is not a wheel that will cop a beating. Should I get a KTM hub and Excell rim and get it built or........... ?

    I would go with a KTM hub and custom laced front.

    Why would you do that? If you want it lower than lower the bike properly through your suspension and have your stands shortened to fit. Mounting a 17 front and matching it to your 18 rear is foolish. You are just going to drop the front and screw up your steering geometry. Maybe make it dangerous to ride.

    IMO just sell the bike and get something that fits your needs better.

    Fit a 19" front with road tyre. The handling will be sharper, ideal for road use.

    Dont listen to those who have not tried it ;)

    I have a standard 18" rear and a 19" front with contitrail attacks as a road set no problems get on the corners

    I think that is the answer. I wasnt sure if 17 front was a good idea.

    Cheers.

    Nice set up on that SE! Ever wish for the fairing/wind protection of an Adventure?

    On the Bridgestone web site you can compare the OD of the 21" tire to that of the 19". I found:
    21" tire OD = 662mm = 26.1" Tire here is BW501 100/80-19 (street oriented, tube type)
    21" tire OD = 698mm = 27.5" Tire here is TW301 90/90-21 (dirt oriented, tube type)
    19" tire OD = 669mm = 26.3" Tire here is BW501 110/80-19 (2.5" rim width recommended; this is a tubeless tire)

    The front end will drop half the OD difference = 0.1" to 0.7" depending on which tire is compared.
    The rear height change also needs to be compared. Getting a lower profile street tire will like drop the rear to some extent.
    I couldn't find OD spec for Pirelli or Continental tires

    18 rear + 19 front is a good solution if you want better performance on the pavement. Even just putting on a ContiTrailAttack looks like a good street tire even in 21".

    It would be nice to have two complete wheels sets, one dirt oriented and one just for the street.

    Has to be one of the BEST things you can do with the bike ( like two bike's in one, great in the dirt and the street)

    Whole change takes 15 min. It's not cheap, but well worth it.

    I really like it ! Would love to have 2 whole sets,.

    How do you like the Rec..... seat.
    I even have a softer aftermarket, but even that is not ideal.
