GDR have another read of Johhny O post you may be confused.
Various versions of these bikes were raced by Aberg in World championship's with great success, also considering the weight disadvantage up againgst lightweight factory Japanese bikes.
I have a friend who has a genuine Pro-Fab HL and the bike steers and tracks superbly.

I have a genuine real Torsten Hallman Aberg and I have had it since I was young enough and fast enough to ride it, (over 30 years ago)
It tracks superbly but it doesn't steer
I have a C&J XR500 it steers and tracks and is so much better to ride than the TT

The HL was a little dated when the C&J 500 Hondas hit the market.. Things changed fast in the late 70's early 80's.

My C&J 500 is the 79 built Alan West bike on the Revs cover
My Aberg was built in 78/79 I have owned it since 1980

Graeme the Aberg you have would be a very early build as I remember it racing in mid 78. The original owner told me that it took ages to get it from the UK so I would suspect it was an early one. When did the first original HL frame kits become available?

Interesting that Johnson's and Lechein's bikes had a different swingarm....and forks to this one? I thought Johnson ran the #22 in '82 and Lechein ran #224 ?

The first HL500 was built in '77 a couple of years before the C&J.. As i said earlier technology changed rapidly in the late 70's and the HL frame design was soon outdated.

Greg Ian's bike is a US Hallman not UK / NL HL
Johnny O I certainly remember Vertually every change on everything MX from H S and Y from 76 to 85
it's not the technology changes that made the Honda better it, the Aberg has no steering lock and it was/is too tall, the C&J was based on the 78/79 CR250R which had steering lock and did turn.
I raced the Aberg at Jilliby, Dunlop Lea and Foster Park, it only worked for me at Jilliby with its berms, Dunlop Lea was a killer with the deep sand and ruts, Foster Park was fun.
I rode both bikes as registered trail bikes but there is no comparison.
I have CCMs and other trick Thumpers but the C&J is the best so far,
I say so far since I honestly think the HS that GMC has built will be even better,

I'm glad you gave me a bit of a comparison between them.. I want a 4stroke Evo bike and i'm tossing up between a few. Where does a '79 CCM fit in? and the other i'm thinking about is another '84 510 Husky(had one a few years back)

Funny thing is, the 78/79 CR250R is also based on the Husky frame

Too true.. for some reason the HL rear shock position ended up more upright though and Honda pulled the rake in a bit more

So did Ian get his through the UK as that was the impression he gave me when we were talking at Bulahdelah last year. The Hallman bikes were later right?

That is the problem your memory on exact timing fades over the years. The reason I thought it was '78 was I thought I raced him on my VB360 but the VE414 came out in mid '78 and I rode that during late '78 and most part of '79.
