  • Easy to fit with instructions provided.
  • The adjusters allow you to easily adjust the pre-load on the front end.  Allowing fine tuning of the feel of your bike and make it perfect for you.

Seems like a good improvement

They work well, it's a shame about the high amount of import taxes (in Italy) and shipping costs, which raise the cost dramatically, making the purchase less convenient.
