Title: GMC HS 499
Post by: GMC on February 12, 2013, 05:18:32 pm
In the four stroke revolution of the 70’s there was the Hallman / Lundin Aberg Yamaha 500
Then along came the Hallman kits for Suzuki and Honda.
The Hallman Suzuki kit for the SP 370 and DR 400 looked like this…

MX action did a story on one… (same one going by the race No)

I was then lent a genuine frame some time back ( Thanks to a Forum member ) and after a few false starts and other distractions I now have the first replica kit ready for assembly.

It’s a ‘carbon copy’ of the original except I have added different footpeg mounts as the original spline system is not only awkward to produce they are also awkward  to set up a decent peg on.

The bare frame weighs in at 8.8 Kg

A bit more chain clearance has been added to allow for modern X ring chains that are wider than normal chains.

The original frame was set up to suit the Yamaha YZ 125 seat.
I have set the jig up for this seat but I can also set up to suit other seats if desired.
This frame was set up for the RM 250 C seat.

Information on these frames is scarce as I don’t believe they made very many of them so if you know of any other frames in existence or any other articles or history on them I would be keen to hear about it.

Now to get onto the swingarm and airbox…



A forum member on here is making some stroker cranks to take the DR 400 out to 499

I knocked back a reasonably original and running sp370 that was only $300! about 6 months ago. Once the good folk get hold of these frames I doubt we'll ever see another $300 running sp370 again!!! Good work Geoff, I'm sure you've just won a whole new legion of fans!  8)

Cheers, Brendan

I forgot to thank former Boolaroo Suzuki Dealer Alan Craig who donated a set of the Kayaba Air Shox to the project, they are as rare as the Hallman frame.

What about the paddock in the photo background,
Looks like a great location for a grass track

Yep that paddock be in Broadford Victoria, might be just the place to build a few various motorcycle race tracks.... ;)
Hey Geoff how are your flocks of Yowies, Bunyips and Drop Bears going?

Yes it was very generous considering I kept slipping it onto the back burner.

Awesome work Geoff  8)

Absolutely correct Simmo, that’s exactly how much they are*







*$ 795.00 plus average 3.95% CPI from 1980 to 2013 makes them $ 2970.00 today

Frames are sold in bare steel

Yes the swingarm will be the same style as the Profab arm that's in the above pictures.

According to reports the SP370 cases can have a problem that was rectified in the SP/DR 400,
That said I am still using SP 370 cases in my bike.
