Comfort and Handling
The ST1300 provides very good comfort for a sport-touring bike, though not quite at Gold Wing standards.
We can say the motorcycle handles well despite its weight.
One won’t feel confident on the ST1300 after speeds of 90 mph. The motorcycle feels wobbly at high speeds.
One can adjust the rear shock absorber to stiffen up the rear for a firmer ride.
If this doesn’t feel enough, you can improve the handling in your ST1300 by upgrading the suspension setup.
Honda ST1300 Preload Adjustment
To adjust the preload on your ST1300’s rear shock, you will need a C-spanner to loosen the top locking ring and spin up the shock to gain access to the adjuster ring.
If you want to increase preload so the spring has less travel and to make the bike feel stiffer, turn the adjuster ring clockwise.
Honda ST1300 Suspension vs Rivals
Suspension can be adjusted on the FJR1300 from the dash, both on pre-load and damping. The FJR1300 provides a smoother ride compared to the ST1300.
You won’t feel as confident with the ST1300 at high speeds as the FJR.

Honda ST1300 Suspension Review
The ST1300 has a compliant, comfort-oriented, adjustable suspension suitable for touring. It provides a smooth ride but lacks sportiness.
Front-end dive under braking can be excessive.
Ride quality is plush and comfortable at lower speeds but the chassis can feel vague when pushed.
Progressive rear shock suits heavier loads but can feel soft without luggage or passengers.
Wheel travel is generous and soaks up bumps well. Compression damping could be stiffer for sportier handling.
Dive from the front end under hard braking affects handling. Aftermarket fork springs can improve this.
Honda ST1300 Suspension Upgrade
The ST1300’s suspension is under-sprung and softly damped.
Such a suspension setup impacts braking performance. reduced resistance to bottoming out, and increased harshness at higher speeds.
Honda ST1300 suspension upgrades include the installation of a 640 Wilbers rear shock with a remote preload adjuster and progressive springs for the forks. This setup costs around $1400.
Install heavier fork springs on the front suspension and re-valve them for improved performance.
Adjust the rear suspension with a heavier spring for solo and two-up riding. Do a test ride and adjust the preload according to your preferences to complete the ST1300 suspension upgrade.
