I have a 2016 FXS which I have been adjusting to my riding needs. In my case this means dual use with combined riding in grass/wood lands and asphalt.
Tires have been changed to Conti Escapes.
Forks lowered by 2 inches in the triple clamps.
Rear shock is one of two brands. The first is a Ikon "special" made for me and a spring for my weight.
The second shock is the original Showa heavily modified with a new threaded spring sleeve machined and installed after a lowering kit.
The seat is thinned down to reduce the height by 1 inch.
As to the original suspension design of the FXS, it is ill designed. Understand that I have raced GP, MX, Cow Trails, Woods and some of that riding was on an OSSA Pioneer, Cushman, Kawasakis and others.
I do not understand why ZERO did not hire a suspension designer that comprehended the term SUSPENSION. As stock the 8 plus inches of rear travel on a 290 lb Bike that comes with a spring so stiff that a rider of 160 pounds cannot adjust sag is a waste of air.
The ride height/seat height is currently at 30 inches, the rear sag is at 1/2 of an inch and a easy bounce of my rear will move it down a bit more.
After 9 months I am now pleasantly surprised each time I ride this FXS and I would be happy to talk to ZERO on what real bikes should do.
The FXS is a Great Bike and needs some simple intelligent changes to provide a more enjoyable ride.
