Bel-Ray99350-B1LW High Performance Fork Oil - 30W - 1L.

works great, changed my Honda Grom fork oil from 5W to the bell-ray 30 weight and it stiffened my forks so they don't bottom out on bumps now

Works great in my honda grom and clone to make that stiff suspension out by not hitting so hard and not bottoming out anymore 30wt

Converted a '97 Honda XR80 to a mini-moto racer and lowered the front end. I think the manual calls for something lighter like a 10- or 15-weight oil, but I wanted to go higher because it won't be going off-road anymore and I wanted to reduce the chance that the wheel would collide with the fender after sliding the forks up a couple of inches. My dear friend warned me that 30-weight was going to be entirely too stiff. After the rebuild (did not change springs, did not cut springs, did not install bushings), he admitted to being wrong as the front end was the perfect balance of stiffness and shock absorption. I can slam on the brakes and the front end refuses to dive, but I can also hit a speedbump at 60 mph like its nothing. 10/10 would buy again.

Fluid served my purpose. Seems quality and worked well. I needed a heavy weight fork oil for mixing with some fluid of lighter viscosity that didn't give the rebound dampening I wanted. Wish it was a true synthetic but I needed the viscosity so I went ahead and purchased it. Good price and shipping.

Yes. I used it on my motorcycles. Works great

Delivery good. Product works fine in vintage Matchless forks.

I weigh in at 220lbs and this was a great improvement over stock oil in Honda from forks.

Hard to find oil for old bikes but they had it at a great price!
