Review on 🏍️ VOFONO Black 90 Degree CNC Motorcycle Tire Valve Stems for Harley Davidson, BMW, Honda, Kawasaki, Suzuki, Yamaha, Triumph Bikes: Easy Install, 10-11.3mm Diameter by Jerry Olson

They fit stock Ninja 250 tires much easier. Mounted to face the right side of the bike as recommended, forget where. The lover did so much that in the end after 5,000 miles of driving he decided not to wait for my front tire to wear out and proceeded with the assembly. Note that the channel on the front wheel is smaller than the channel on the rear wheel. You can still install it, but I had to use a wrench instead of a socket. (I'll upload a photo of the front wheel if I find it.)
