Hyperpro progressive fork springs for the Triumph Street Twin 900, for more comfort, stability and precision

These Hyperpro progressive fork springs were selected by FCR Accessoires to upgrade the front end of your Triumph Street Twin 900. Built for road use and long distances, this motorcycle fork springs kit transforms the efficiency and riding comfort of your bike, in the spirit of a real suspension upgrade.

Its first contribution is comfort and road holding. The progressive springs absorb road imperfections better, reduce jolts and vibrations, and offer greater stability in a straight line as well as in corners. The result is a smoother, safer ride, even on poor road surfaces.

The Hyperpro signature is the progressive format. The spring is wound with an asymmetric pitch, the gap between coils varying on purpose, and its dynamic profile is geared towards comfort thanks to the suspension management program developed by Hyperpro. This design improves line precision, especially on corner exit under reacceleration, and can reduce braking distance by up to 20% through better absorption of kinetic energy.

The kit is sold per pair, with the amount of oil needed for a fork oil change (1 litre of SAE 15 supplied). Fitting is original-type, with no permanent modification to the chassis, but it is a full fork oil change that requires strictly respecting the oil level specified by Hyperpro. A job best entrusted to a workshop.

Hyperpro springs come with a lifetime warranty. For a more consistent behaviour, using Hyperpro progressive springs at the front and rear together is recommended. An ideal upgrade for demanding riders, selected by FCR Accessoires for the Street Twin 900.

The advantages of the Progressive Fork Springs Hyperpro | Triumph Street Twin 900

Better stability and road holding

Hyperpro progressive springs optimise the distribution of forces and the balance of the bike, in a straight line as well as in corners. The feeling of control is reinforced, for a smoother, safer ride in varied conditions.

Optimised damping and comfort

The progressive format absorbs road imperfections better and reduces jolts and vibrations. Comfort at the wrists and forearms is clearly improved, ideal for covering long distances, even on poorly maintained roads.

Line precision and braking

The fork gains in precision, especially on corner exit under reacceleration. Thanks to better absorption of kinetic energy, these springs can reduce braking distance by up to 20%, for a more dynamic and safer ride.

Frequently asked questions about THE Progressive Fork Springs Hyperpro | Triumph Street Twin 900

❯ Why fit progressive fork springs on your motorcycle?

You fit progressive fork springs first to gain in comfort and road holding. Unlike a standard spring with a constant pitch, a progressive spring stiffens gradually, which absorbs small imperfections better while handling big hits. The result is a smoother ride, better stability and greater line precision. It is one of the most effective suspension upgrades for road use on a neo-retro motorcycle.

❯ What is a Hyperpro progressive fork spring?

A Hyperpro progressive spring is wound with an asymmetric pitch, meaning the gap between coils varies on purpose along the spring. This design, driven by the Hyperpro suspension management program, gears the dynamic profile towards comfort. In practice, the fork stays supple over small bumps and firms up under heavy loads. Hyperpro springs also come with a lifetime warranty.

❯ Is this kit compatible with my motorcycle?

This kit (Hyperpro ref SP-TR09-SSA025) is designed for the Triumph Street Twin 900, model years 2016 to 2019. It has a frame number restriction: it applies to Street Twin 900 models with a VIN before 914972 or 917474. Check your frame number before ordering. If you are unsure about your version or model year, confirm compatibility with us.

❯ How do you fit this fork springs kit?

Fitting is a full fork oil change, best entrusted to a workshop: 1) Remove and drain the fork tubes. 2) Replace the original springs with the Hyperpro progressive springs. 3) Fill with the supplied oil (SAE 15). 4) Carefully set the oil level to the mark specified by Hyperpro (oil level 120 mm, air gap) in each tube. 5) Reassemble the fork. Fitting is original-type, with no permanent modification to the chassis, but it calls for method and tools.

❯ Do you have to change the fork oil and which one to use?

Yes, fitting the springs requires a fork oil change. The oil is supplied in the kit: 1 litre of SAE 15, whose grade was chosen by Hyperpro to match the springs. This grade must not be changed. For subsequent oil changes, it is recommended to use Hyperpro oil of the same grade. The crucial point remains respecting the specified oil level.

❯ What are the concrete benefits on the ride?

Progressive springs improve comfort, stability and line precision. They reduce the jolts and vibrations transmitted to the wrists and forearms, which is welcome over long distances. They can also reduce braking distance by up to 20%, thanks to better absorption of kinetic energy. The bike gains in composure as well as in dynamism.
