Ironically I once owned a Rokon, I kept it my ex's place in California to ride when I visited but after a while I sadly I stopped visiting. It was an enduro version and despite the transmissions belt tensioners tendency to slacken off every 20 kilometres or so it was a solid performer.

So some of these flattrackers do not have a front brake, can they run at nepean DT in the same class as the CR's and YZ' run in
You have to run a front brake here, I've put the spool front wheel aside and have fitted a 19" Akront laced up to a YZ Yamaha brake. You can't run these bikes against the moderns these days as the rules state that bikes need stock frames. They're right to run against the stock frames vintage motocrossers though. If someone was in the position to put up a good argument, I reckon you could possibly get away with entering them in any slider only races as it could be argued that these bikes were built with the very same intentions as a Hagon or Elstar.....to go sideways on a dirt track.  ;D ::)

You betcha Brett ;D. I'm planning on taking it to the May practice day to run it (and myself*) in and tune it. If my health and riding skills come back a tad more I'd like to debut it at the Charity Meeting later in the year. If I'm not up to it yet I'll let a mate race it at that meet.

* Because of my then declining health I haven't ridden on a race track since the early noughties so even though I'm much, much healthier it's still going to take a lot of practice for me to get back up to reasonable race speeds. ;D

It's a Fastrack this week Jim ;D, it changes all the time. I've had people on three continents offering up their suggestions as to who might have made it and Fasttrack has the most votes from folks the USA. It's not Champion, PDV, Knight,Trackmaster, Redline, (Jerry) Cheney and C&J. It's been suggested that it might be a Boss frame but I don't think so. Whatever it is it's professionally made and really well TIG welded. I still think it looks closer to a Fastrack than anything else....remembering that it's 0001 frame number which would possibly make it a lot different to frames that came later.

Here's a Boss frame compared to mine....close but no cigar.
                                                            
                                                            
                                                             
This is the area of the bike that separates it from others and should make it identifiable, the above swingarm brake stay and lack of rear frame loop are fairly uncommon design facets.

(Nearly)Finished:  
Well the little flat tracker is just about finished. All it needs is a chain, shorter front brake cable and fluids. It's a bit of a mystery as to what the frame is, we've narrowed it down to a Boss or Cycle Centre frame but in reality we're still guessing. Whoever made it it's a beautifully light, tig welded frame with a lot of 'different' ideas. I do however know that the engine's a piston port 360 RT1 Yamaha with DT2MX gears, balanced 'Franks Cranks' crankshaft, ,mild porting, Single ring RT1MX piston, PVL ignition, 38mm Mikuni, Jemco flat track pipe. The rear wheel is from an MX250 with a Mitas trials tyre, the front is a 19" Akront rim laced to a MX250 hub with a Dunlop K180 tyre. The rear shocks are Gazi's, forks are from an RD250 Yamaha. Handlebars are inter-Am solid alloy with Magura levers and throttle. Yamaha MX grey cables. The tank is a small Champion version and the seat is early Champion big bike version. It's painted candy apple red by me. The engine will eventually go back in my Cheney pre 65 motocrosser and be replaced by a DT2MX reed engine on methanol for the 250 class as my upcoming 750 Yamaha will cover the big classes. I hope to get it sorted at the next Nepean practice day and debut her at the Charity meeting late in the year.

Very nice job Uncle Firks!

There must be something in this dirt track thing, judging by the amount of traffic on the forum, in this area.

Well done, send some photos of it in action!

I've loved Candy Apple Red ever since I first saw Johnny Stewart's McGee-Shell-Trackburner midget speedcar at the Sydney Showground Speedway in the sixties. Then when I saw Husky Pete's candy red Huskys it became a no brainer as to what colour to paint it. However, seeing that my new Shell-OW72 750 Yamaha is painted in mid seventies Yellow, black and white Yamaha works colours, I'm considering painting this little bike to match its new partner in crime. I've already got the black and white stripe graphics so once the big bike gets here I'll match the shade of yellow to it and possibly paint the little bike. The candy reds not disappearing though, I've got plenty of paint left so I'll probably paint the tank highlights on my pre 60 TriBSA that colour.

Here's a tracker with the same bodywork and the same graphics kit I bought.....what do you guys think....red or yellow?
