Front progressive forks.. Speed Twin

Fitted them myself yesterday and took about an hour.... so really easy. Instructions could have a few more bits of information, but I have a Haynes manual for torque settings!

Happy with the quality, ecstatic about the value and even on my first run this morning I could feel the difference. Less bounce, more control, and certainly more stable than standard. Can't wait until they bed in and I can play with the adjusters! Brilliant. Thanks.
