Suspension

The 2025 Evo Factory range features a new front fork with 39 mm tubes, 1 mm larger than the previous model. This increased diameter leads to an increase in the rigidity at the front wheel, improving the precision and ease of the bike's ride. The fork utilizes a single-sided spring on one side while all of the dampening is handled from the other side. This system allows for a quicker-responding front fork action while saving weight at the same time. The internal cartridge rod is larger and hard anodized for durability and performance. Both stanchions are fitted with convenient adjusters controlled by anodized hex socket screws in different colors. Adjustment is included for over-all dampening as well as spring preload. The fork is finished off with a special TiN gold hard coating which reduces friction while also giving the bike a stunning look.

Triple clamps

Machined from billet aluminum with blue anodized finish providing rigidity and lightness (weighing around 3.5 ounces less than standard models), they also feature fore-aft adjustable handlebar brackets to let the rider find their ideal position. The new blue color also adds to the bike’s overall Factory look.

Blue anodized handlebar

The new blue over-sized Reikon handlebar retains the exemplary flexibility which sets it apart, now guaranteeing a zero-compromise look.

Footpegs

Black machined billet aluminum, durable yet lightweight with the non-slip steel pins ensuring maximum grip.

Wheels

Stunning blue wheels complete the overall look. Tubeless rear tire provides the ultimate traction.
