The swingarm is much thinner than a layman like me would expect it to be. Not really a huge deal as most swingarms were already drilled from the factory anyway.Not having to drill the swing arm would be a bonus.
Easier if you have someone to hold it while you mark.Am just about to do the same on my B4, so this saved me asking the question! However, I do have one more to ask, that is, does the hugger locate accurately when holding it in place to mark the holes to be drilled? Just don't want a wonky hugger!!
