I fitted Oxford Products Universal hand guards to my SP401. I did a post about it a while back, but if I try to link to it, this post will just disappear into “Awaiting moderation” limbo for days. My post (with pics) is located in the Svartpilen 401 Parts and accessories section.
I’ve had no problems at all, couldn’t tell any difference vibes-wise compared to before I fitted them . I was worried they might cause problems because I had to remove the internal bar end weights to fit them, but actually I have had no issues. They look cool and suit the bike, and work well at shielding my hands from the worst of the wind.
I’m interested inthe lever protectors you mentioned. I wonder if its any better to do full on hand guards, or get the protectors. I have bar end mirrors atm, haven’t had the chance to use them yet because I have some work to do on the bike first.
