SIRRIS - Trail Tune Forks - Ultra Bee

The stock Ultra Bee fork holds up fine until you start pushing the bike harder than it was built for, and that's exactly the gap this Sirris F43 was designed to close. It's a true symmetrical closed-cartridge unit with separate lubrication and damping oil circuits, so the damping stays consistent instead of fading out halfway through a ride. Sirris built this fork with engineers who came out of Fox and Ohlins, and it shows in details like the hydraulic bump stop, which softens hard landings instead of letting you feel every bit of a max-stroke hit. This particular unit is the Trail Tune in the Light spring configuration, tuned for riders in the 130 to 160 pound range without gear, so double check that weight window fits your customer before it ships. Installation is genuinely plug and play, with the dust seal and headset bearing already mounted on the steerer tube and full compatibility with the Ultra Bee's factory display, fender, brake caliper, and fairing. Riders who've put real trail and race miles on this fork describe it as the single biggest transformation they've made to the bike, closer to a real dirt bike than a stock Ultra Bee ever feels.
