Original pads worked well and by approx 6500 miles were getting a bit thin. Although serviceable I decided to change them partly to get the piston further back into the caliper housing as excess road muck (from work) meant in winter I was having to clean them every few weeks. Don't know if it will work but for approx £10 it was worth doing.
Good points Not too expensive
Organic compound
Quick bed in
Work well in the wet
Similar feel to Yamaha original fitment
Strong braking performance like the originals
Bad points None really so far
Only slight difference is these don't have grooves in them. Not a bad point tho.
