The scoot's pretty heavy so with a single sliding caliper at the front, a high fiction pad would certainly be favorable.
So, any branded pad with HH rating would be best IMHO.
Brands like Vesrah, Goldfren, EBC, DP should be safe bets.
Only 4000 miles on them. The levers do pull back a little more but not bad. SO if it is pads on both ends what would be a good pad to replace them with then? I cna be a little heavy on the breaking so I certainly could be worn done al ready.
