I used the Motorcycle Formula ride on for my front and rear. I've been exceedingly happy with it!
It took about 20 fl Oz to fill both front (I run a 5.10 size 244 up front) and rear tires according to the RideOn "Heavy Duty Application" dosing formula. That means buying 3 of the little 8oz bottles the first go-round .
I guess I've had it in there for about 1000 miles now, my only regret is not putting it in there sooner! The sealing properties are the main reason I invested in RideOn, but after putting it in I have really come to appreciate what an impeccable balancing job it does. Makes for a MUCH smoother ride!
I've posted about how much I love RideOn before: https://tw200forum.com/forum/general-...ight-ride.html
