Ok no doubt going to sound like a daft question to you guys but want to convert my CRF70 to rear disc brake set-up. Seen lodsa people have done it which swingarm and disc brake set up is most commonly used?

Want it done properly as I'm a rather aggresive rider,been looking to uprate the swinging arm at the same time what do you recommend for the whole set up inc rear brake? Seen a few people use mountain bike 6pot Hope set ups? Is this a self build or does anyone sell the kit to bolt straight on?

I'm based in the UK and the 70's aren't so common out here so proving to be a tad difficult soursing parts like this...

Cheers

Well I think theres really 3 other ways. One is to use a +4 crf50 swinger and lace a BBR crf50 disc kit to a 12" wheel. Another way is to use the reeg 70 setup but those are extremely rare these days. The last way is to get out the welder!

You mention a +4 swingarm kit... Who's make is that? Had a look at a couple of option Reeg was one of them but as you say there very rare it seems...
I knew the CRF50 swinging arm kit fitted but haven't seen a +4 option yet only 2 1/2 and 3...
Can easily get a BBR CRF50 disc set up as have a trade account with them AS LONG AS THEY REPLY TO MY EMAILS...:confused: and they haven't discontinued the set up...
Lacing a 12'' wheel would be simple also as live a few miles from a wheel building company...

Sano and five 0 are two companies that I know that made +4 swingers for 50s, which works out to a +2 on a 70. Good lucking finding one new. BBR has most of the parts for the rear disc kit last time I talked to them which was a few weeks. Call them for the best results, or pm them through this website, they have an account.

Cheers chap you've been loads of help,will crack on and try and track a +4 swinger down then... Needle in a haystack springs to mind but wish me luck!
Job to call them from the Uk as never sure of the best time... Will try and PM them on here. :)
