Preface: Did a forum search, didn't quite find my answer.

Was just wondering what USD forks are best for a MC21 (my forks are slightly bent, need new tubes), other than RVF400 forks. I've heard of guys using CBR954/929 forks, RGV forks and RS250 forks. Any ideas?

I know the main issue is the bearings fitting but hoping someone may be able to provide some insight. Cheers.

(By the way, RVF400 forks are quite hard to come by in my area. People snap them up quick for similar conversions on MC22s as well).
