Fitted the progressive springs, pre-load adjusters, cartridge emulators, and piggy-back rear shocks to my 2011 SE Bonnie.

Just did a 200km fang around some of North Queensland's country roads and I couldn't be happier. Rough and damaged road surfaces just ironed out and the whole bike just feels planted. Well done TEC.

Improved ride with progressive front fork springs

Easy to fit, not much money and there is a noticeable improvement in the ride without compromising handling. They have reduced the shock to my lower back quite noticeably. I guess the rear shocks aren’t having to do as much now with the front end absorbing more of the bumps and lumps....
