(( other model fitments available by request ))
As with all belt manufactures ...there will NOT be any warranty returns
as they will not except any returns due to varied fitment  conditions  beyond their control
Belt tension setting tools & alignment equipment are available. Remember to do belt tension check and adjustment after 50 or so miles, along with 250 & 500 & 1000 miles, along with your models maintainance schedule.

 It is always best to understand why it needed replacement in the first place ....as the life of the belt will be shortened, if there is an ongoing problem for example... if you have a worn or damaged front or rear pulley, or a misalignment between them.
Check your Lower Belt guards actually do prevent stones from entering between pulley & belt and punching through,
and that the correction tension is applied.
