FDS-250 Fork Damper System GSX-R125 / 150

．Applicable Models: SUZUKI GSX-R125/150

FDS – 250 Series ．Preload Adjuster: Please use a 12mm socket for adjustment. One turn equals 1mm, with a maximum range of 10 ± 0.5mm. There is a scale on the side of the adjustment rod for quick and easy setting. ．NTN Needle Bearing: Built-in NTN needle bearing to reduce friction when adjusting the preload head. ．Lightweight Preload Spacer: Note that when installing, the black plastic side should face the spring end. After calculating the required stroke, replace excess spring with lightweight spacers. ．Reinforced Spring: The spring uses SAE9254 silicon steel material to create a lightweight spring with a larger wire pitch. ．High-Sensitivity Valve Piston (W.R.V.P): Precisely calculated high-sensitivity valve shim settings, combined with a large piston featuring independent one-way damping for rebound and compression, provide the necessary damping force for low, medium, and high-speed operation. This eliminates unnecessary simple harmonic motion (S.H.M.), providing the tire with maximum normal force and maximum static friction at all times. ．Compact Size + Lightweight Piston Rod: The piston rod volume is reduced to increase the internal oil volume of the front fork, stabilizing oil temperature and damping force. The piston rod is made of high-tensile aerospace-grade aluminum to achieve weight reduction.

※The vehicle model may have different specifications in different regions and may not be compatible for installation.

[Notes Before Ordering] Before ordering, please carefully confirm the color, size, and other information you wish to purchase. Most products have lead times provided after the order is placed, so there may be situations where products are discontinued or require a long wait for shipment. If an order cannot be fulfilled due to manufacturer stock shortages or temporary unavailability, it will not be processed; no fees will be charged if the order is not established. Please note that manufacturers may unilaterally change specifications or exterior designs, resulting in packaging or product styling that differs from the images on the product page. If a manufacturer's unilateral change in product design or specifications prevents the product from performing its intended function as expected at the time of purchase, please consult our customer service for further processing. Products go through multiple shipping processes from order to delivery, so packaging may be deformed or damaged during transit, but the product itself remains intact and functional. [Return Policy] If you need to return a product, please apply in the return section; please keep the product appearance intact and seal it in its original packaging box. Upon receiving your return request, we will dispatch a logistics provider to collect the goods as soon as possible. For non-human-induced defects, please apply for a return within 7 days of receiving the product. [Authenticity Guarantee] For products with an authenticity guarantee, if they are found to be suspected counterfeits and confirmed by a court judgment after relevant litigation, we will compensate the customer 10 times the original purchase price.
