Hi I would like to know how weight and oil in front fork?
It depends on the make of the bike, its type and model/year. In small bikes there can be as little oil in the front forks as 1/4 of a quart or liter, in bigger bikes the amount may be haf a quaet or liter or more. The problem with adding oil to front forks is that bigger bikes need to be jacked or lifted up at the front to fully extend the springs inside so that enough space is made for the new fork oil. The bolts on top of the front forks have to be removed with a wrench and then the oil is poured into the hole. Use a funnel to prevent spillage. If your front forks are leaking the oil you must get new front fork seals. Select thin oil for the forks, 5 W, 10 W or 15 W at the most.
