Changed Rear Tire: Saddle Height is Too High

[mouradjan]

Original tire 130/90-15 and 130/70-17 is same in diameter.i used my bike about 4000 miles and changed my rear tire with 17 inch rim.i used a 130/80-17 k761 on rear.it changed the driving geometry of the bike. The rear is about 1.7 cm taller now.And the rear suspension has less working area that isn't better like 130/90-15 original Rx3.
I need some help. Do i have to use a lowering link? Or do i have to higher the front suspension.?

Since you own a bike other than the Zongshen RX3, I don't think the RX3 lowering link will fit your bike. I have moved your question to the Dual Sport Forum, where you will get better answers for this suspension question.

so the tire itself should be only 1" taller in diameter. so that is only 1/2" (~1cm) at the axle.


lowering the bike will only reduce your available suspension travel more. unless you are rubbing the tire on the underside of the seat I would not worry about it.


if you find that geometry bothers you then you could increase your sag a little to lower the back or raise the front
