    Has anyone adjusted the preload for their weight, and any tips if you did. Or did your dealer adjust the rear spring preload when you took delivery of the bike?

    Yes, I made mine a couple of clicks stiffer. It’s in the manual how to do it but the combination of quite fiddly positioning and the clicker being very stiff made it a much harder thing to do than it should be!

    For a newbie … what is the purpose of change it? Is it depending on my weight or road/of road driving?

    With the spring preload you adjust the SAG number, witch, as a rule of thumb, should be 2/3 of your suspension travel when you sit on the bike. In the case of the 701 the number is about 90 mm (for 135 mm of back suspension travel).

    So, you measure from the back wheel axle to the “VITPILEN” writing on the tail, with no load on the bike (A), and then you get on the bike, in full gear, and have a friend take the same measurement (B), and do the math.

    A – B sould be around 90 mm. If it’s larger than 90 you should decrease the prealod, and the opposite if A-B is lower than 90. Re do the B measurement every time you change the preaload, and once in a while…

    Regards.

    I’m sorry guys… I made a mistake. the SAG number is 1/3 of max suspension travel, so, in the case of the 701 it should be around 45 mm.

     

    So, when you do the math, A-B,  45mm is the number you should be aiming at when you ajust the SAG.

    regards.

    Thanks Razvan for the explanation! Where can I find the measurements for max suspension travel for the 401?

    On the official Husqvara website the spec is 142mm front and 150mm back suspention travel. So the number is 150mm, so, in tis chase your back SAG nunmber is 50mm.

    Regards.
