The Sirris F43 fork: Revolutionary suspension for e-moto enthusiasts

The Sirris F43 fork is the ultimate upgrade solution for riders of compact electric motocross bikes such as the Surron Ultra Bee, Talaria MX5, or E-Ride Pro SR. As a high-end suspension fork specially designed for aggressive off-road adventures, it combines precision engineering with robust construction to offer you unmatched control and comfort. Whether on demanding trails or fast-paced MX tracks, the F43 transforms your machine into a true racing monster.

With an impressive 246 mm of travel (260 mm on the EBMX version), the Sirris F43 absorbs shocks seamlessly and ensures a smooth landing after high jumps. The oversized 43 mm stanchions and closed-cartridge shock provide minimal flex, resulting in more precise handling in corners and at high speeds. Compared to standard forks, it offers 20 mm more travel, giving your front end more buffer space on rough terrain.

The CMX-Tune variant (Compact Motocross) is perfectly tuned for compact e-motorbikes and ensures maximum stability on whoops and big airs. Sirris has rider-tested and continuously optimized the fork to minimize friction—after a 5-hour break-in period, it unleashes its full potential. The firm suspension adapts dynamically without compromising the agility of your bike.

Adaptability is a hallmark of the F43: choose from several weight ranges (up to six options for trail or MX tunes) to tailor the suspension precisely to your riding weight. Whether medium or heavy tune, you can calibrate the fork individually with precise settings for compression, rebound, and preload. In addition, the high-strength fork protectors made of PP material protect against dents and scratches, even at 210 degrees.

In summary, the Sirris F43 is not just an accessory, but a game changer for e-moto riders who want more. Combine it with a matching rear shock such as the EXT Arma or Ohlins TTX22M for optimal performance. Bolt-on installation and compatibility with stock components make the switch easy—get ready for a new level of confidence and fun.
