That is a sweet conversion for sure. I've seen that ad on ebay though and they want way too much for that front end setup (like $1000 or something). You could put it together yourself way cheaper with some used take-off Zokes off a KTM 50

Smokin deal that I'd like to get myself but..............! God that would be a sweet frontend set-up for my SS50 build!
This is my next summers build. Going to try to find a ktm 50 pro sr. frontend like that or a whole bike since I may use the ktm 50s headtube and weld it on the crf 50 frame.
Going to use that disk frontend and for the rear going to attempt a kx 65 swingarm and might try to use the kx 65 lingage system too.
Should be a sweet build and it will a decently cheap one!

I grafted the whole CRX50 Polini disc front end (Bars, levers, tree, brake setup, forks, rim & tire) I scored off fleabay for my sons 50. At 33mm forks, its the same front end setup on the earlier model KTM 50 Seniors. Also swaped in the Polini rear coil off the shock onto a fastace adjustable to give it overall the right balance for my 10 year old son. Went for a genuine CRF70 throttle to fit the bars, then all sweet.
2 versions of fork lengths on the KTM's 50 & 65's are about, so shop carefully - longer ones will need some serious rear end balancing - the 50 caliber 3+swingarm is ideal for raising the rear if you go serious like I did.
I bought taper replacement bearings & replaced the seats in the stock XR frame head stem. Some work was required machining to fit the new bearings on the tree, and on full lock the upper fork brace touches the tank restricting full lock turns, but doesn't impact on overall riding. It would be nice to get a 100% fitting tree like a Marchonni but the triple tree costs more than the whole CRX50 I stripped for parts ! I've recently bought a 2003 RM65 33mm triple tree & mock fitted up. It will require a new smaller centre shaft, but with a new machined shaft and spacer on top of the top bearing it will give me the lift needed to clear any tank fouling issues, as well as raise the bars so that any standard MX bar can be used rather than the traditional 6" rise bars.
I'm amazed at the current outcome though - with 9" both front & rear I can ride both my xr600 and my sons xr50 around the same track and both feel near the same. Although the 50 has softer suspension for his lighter weight it soaks up everything without bottoming & without missing a beat with me on board. Scary in fact as you end up at the same speed as my fullsize, but with only 10" rubber between me and the ground it makes me want to backoff !!
I would have no hesitation in recommending the KTM front end swap in
