510 flattracker on EXIF

Interesting, I like it alot. Not a fan of the site which usually has endless firestone tyred faux cafe racers but here's the link.

Very nice, but I would have liked to see twin Ohlin shocks.

Cheers, Dave.

Have just rid myself of a Husky 630SM ... and purchased this CCM 710 flattracker (not registered yet, but I´m fighting my way through the German TÜV red tape)

n

cant say im a fan..looks very mismatched

I agree. It looks a little out of proportion !
Nice bike though.

Just wish I had that engine for my next project. Any generous donors out there interested in sponsoring a 4T Husky motor for a Sugar Bear supermoto replica? Hmm, thought not, will stick with the Husaberg then..

It may be a good bike but it isn't a flat tracker.

Hi Guys,

Bike looks great but it needs a vintage black with silver side panels WR or CR tank.

Cheers, Dave.

Outrageous! I luv it.....and yes, old style colors would top it off nicely

I know it´s not a flattracker (but the nearest think that´s road legel). And I can´t (won´t) change its looks as it´s a hand signed and numbered exclusive by the famous CLEWS. And I agree with the comments on its look ... but that´s what I like about it.

CCM have made and make some good bikes, Its good to see another make along side Husqvarna (to name a few) still going strong with a strong following.

Street legal street trackers:

The old bike shop near me, the orginal owner races dirt track with a 390 auto. I haven't seen him in 15 years.

I built an 82 single shocker too. Using a swing arm from a later bike. My point is the twin shock frame did hold up so why all that steel in the single shock frame. It's over kill.

Husky Reed valve 4 strokes dont last long as dirt trackers. everyone i've seen here on the east coast has blown up horribly. wrecking heads and breaking center cases. best left in the woods and on MX tracks.

Not sure I know about a reed valve 4 stroke? Post a link or elaborate for me cheers.
A pic following on from Xcuvator post. A Harley I did up with Buell stuff a few years ago. Made a perfectly good 1200 sportster overbraked and handling well but then underpowered. Sold it.

I had a 1980 Yamaha 650 special that I wanted to do something like that to. I was in search of a Champion frame when a drunk old man decided to make a left turn and kill my 650 and nearly kill me. I've done some searching for a Harley XR1200x since then but still have reservations when it comes to street riding.

Now you see the light about reeds and 4 st !

Thanks Michel. New to me! Found this English version to match your flow diagram. I just wish I could get my hands on one of these motors....

In 1984 Husqvarna shocked the dirt bike world by introducing a four-stroke design that was both simple, and reliable. Husky at that time was a leading manufacturer of two stroke motocross and enduro machinery, and the introduction of the four stroke TX/TE 510 Husky was unexpected, if anything.

Husqvarna designed the new 510cc four-stroke motor to be simple and light, with an ingenious oiling system that used vacuum produced in the crankcase to lubricate major engine components. Two reed valves in the cam case, that held a pint of motor oil, lubricated the entire motor.

Here’s how it worked: When the piston went up, vacuum was created in the crankcase, and a reed valve at the bottom of the cam case would open, and allow oil to be introduced into the needle roller bearing crankshaft and cylinder assembly.

When the piston came down, the resulting pressure would force the oil out of the crankcase, back into the cam case via a directional reed valve at the top of the cam case. The oil in the cam case also traveled up the cam chain, and lubricated the needle-bearing camshaft and related valve assembly. The air-cooled four stroke top end rested on a 400 Husky 2 stroke lower end, modified to accept this “unique” top-end and oiling system.

The design worked like a charm, and with the exception of running a little on the hot side, the bikes had anvil-like reliability. For some reason Husqvarna dropped this design after a couple years of production, and went the water-cooled route with standard oiling on their next big four-stroke, the 610.

By 1984 the Swedish built Husky was on its way out, soon to be purchased by Italian manufacturer Cagiva in 1987.

The design of the 510 was just a side note in the long illustrious history of Husqvarna design and innovation. Let’s hope under the hand of their new owners, Husky can recover some of that lost magic.
