Flat track frames

[Freakshow]

IM not sure of the frame of the stock 450 but im guessing its not going to be too good more so in the length etc, you could try a 21 inch wheel in it and lowering the seat.

IS the Cb motor mounts similar to anything else ? if it was close to the Xl i would definatly be looking for a trackmaster or sonic for it that would be the go for that puppy.

Youd be surprised how many Dt Bikes are out there looks like firkos mates have got a few , i got about 10, then there is the ones you mentioned so  we are probally looking at 50+ including a few astro already out here.

Where does it alk about a US based track sssion at braodford? i thought it was just Dt ?

im not really up on what the story is with the bonaza thing i cant get my head around what, where and when you can ride, seems a bit confusing to me.  although id like to go up there for a ride

the 450 is a similar shape engine to a XS650 or Triumph so I would probably need a frame to suit one of those but I'm happy for now to have a go at modifying the standard frame, 21 inch front would definitely work better but I want the big chunky look of a 18 or 19 front.

There running a half hour session each day for US Flat track bikes on the dirt track. There is a timetable on the MA site which makes it a bit clearer

[Freakshow]

 you saying you get to only run for 30 mins once a day ?  WTF and they want you to travel KM's for that ?    am i missing somthing ?

[Freakshow]

If your going to go for the pre 70 look you wont need a Am frame as you be using a stock one and the pillion seat, glass sets werent realluy out till 1970's

Which is cool cause stocker back then were set up more as TT or scramble bashers.

Before fremont raceway got turned into an oval track it was a scramble track with left and right corners ans a jump.  MAybe this is the direction you should be thinking of going in

compare that to the tracks they went to  and you can see the frame change

and IM prity sure that video is wrongly titled Alex and Steve eckland rode for Carlo from boss frames, its in the 80's and im sure it was a 500 they both rode cause i new a few strory on that bike at the Astrodome.  any how poinot is PRe 70 vs later is real differant, and that last vid, well point there also is where was the last place you saw a track like that in Au ? which is why the set up dont work so well on what we use for Dt

[Mick22]

Yep 30mins each day for the US flat track bikes, not great but considering that Dirt Track was a complete failure at the CD meetings I'm just glad we're getting any track time at all, hopefully the classic dirt track scene can start to build from here. Guess its only going to suit guys that have a few bikes for the different classes. Its the first time i've seen a ride for US flat track bikes so I'm just hope a few turn up and in turn it spurs a few more to get out and have a ride so we can get a race at meetings as well.

as mark said these dont handle on our dirttrack tracks.if one got in front of you you just road around the outside of him on your 500 slider.in the states the longtrack bikes used to run with us flattrackers in ca years ago.they banned them as to fast and dangerous for the tracks they rode on.kerry i would like to see a 650 triumph flattracker line up aganst cliff patten or any of the ex speedway riders at canberra or nepean.the result back in the 70s was they were not fast enough for a grade riders.most likely the same result today.about 5 years ago there were races at selected trotting tracks in nsw and qld.i saw and spoke to jay springfield at these events and even he said the guys like mick poole ect were crazy riding that fast on these tracks,much faster than him on his factory xr750 harly.ma has just passed a new rule allowing 500cc sliders to run in the unlimited class.we will see if it passes down to classic dirt track.

Jim..They're still running the American flat track class at the country (and some city) long track meetings. There's a good selection of bikes probably 20 in total ranging from Trackmaster and Redline Triumphs... Shell, Champion and C&J Yamahas, a smattering of XR750 Harleys and other tasty stuff. Not all of the bikes turn up at every meeting but they are a tight knit little group with a nucleus in the Kurri Kurri club that do their own self promotion. Jack Stevens is the current hotty with his Nourish Weslake powered Trackmaster but next year Jonesy will have his similar bike out there and Edgar may be persuaded to pull out the ex Eddie Lawson Shell framed OW20 750 Yamaha for a skid or two once he's had his hip replaced. Who knows, I may even be inspired to finish off my 650 Benelli Trackmaster and put a speedway riding mate on it. 

If you add the above group to the 7-10 or so bikes in the Mildura/Western Victoria area and the smattering in country NSW there'd be 30-40 bikes just for an open class. They're more common in OZ than what people think.

Alan Jones at Nepean on Betty but it'll soon be his Wessy 850 Redline

So after reading the above discussion and what Freakshow had enlightened me with respect to american flat track frams in another thread (saved me some serious money). Should i be aquiring a 21" front wheel and run a trials tyre on my Pursang-Astro? Makes sense, however i'll keep the 19" and k180's for Action Park's oiled surface.

A 21" front wheel will affect the bikes geometry as the fork tubes don't slide through the clamps, any suggestions there?

Cheers,
Steve

if i had an astro id be running a 19' , but thats just me.

i know this happens in long track and the guys from kurri all used to ride at the trotting track meeting put on by ivan mauger.but what i was saying they are not realy suited for our smaller dirt tracks.i like them they look nice.i was very impressed by jay at bankstown.he is also a real good bloke to talk to.there is a yong aussie guy racing in the usa at the moment i will get his name from allan he is going great over there even getting into the top line events and at the pointy end as well.he is a exdirttracker

[firko]

I agree Jim. Having owned a couple and ridden a few more including Phippsys wild thing Yamaha I'm certain they're not suited to our tracks. I was just updating your observation that's all. Even if they're wrong for our tracks, they're still cool.

You mean Michael Kirkness ? He is riding for suzuki and beat Chris carr and came second to Jared mees.

 i think used to ride from hastings club up your way, that the one you thinking off ? and only placed in the 2007 Aussie long track

[firko]

Kirkness rode Klub Kevlars resident father figure Phil Youngs OSSA Phantom at the last Port Macquarie (or somewheree up there) dirt trackand he whooped all of the moderns. The kids pretty good.

[jimg1au]

no its not any of those will ring my brother the fossil tonight and ask him.

Speaking of Chris Carr...the XR750 Harley he used to with either the San Jose or Sacremento (or both)miles in 1995 is living in luxury surrounded by a couple of TZ750s, a Manx Norton or two, an ex Gregg Hansford 350 Kawasaki GP bike, the ex Mike Baldwin RC500 and even more exotica right here in Sydney. The bike is fully set up and ready to go. Rumour is that the owner may take it to the Bonanza at Easter.
