History of Nav Gear for Dakar etc
I posted this in the 'Equipment' section, but didn't get any info, so I thought I'd try here.
I'd like to know when the first electric road book holders appeared and who made them.
Even better, I'd be interested in seeing any photos.
I'm thinking late 80's but would be interested in any info and photos of early nav gear of any type.
Thanks in advance.

A few years ago on eBay I saw a road book holder that was actuated by a pushbike type hand brake set up (advancing only as far as I could tell), it still had the original box and I seem to recall the seller saying it came from the 80's.

Unfortunately I didn't win it so I have no more info, and it wasn't what you asked anyway, but I was just curious about the set up and wondered if anyone remembers them.

Oh and I mention it because I have a feeling you want to build a period correct Rallye bike, just giving you options...

tHANKS FOR tHAT. :lol3

I've never heard of those. Would be interesting to see if anyone knows more.

Your assumptions are pretty much correct. I've got a DR750 with some factory bits on it, but despite actually woking on fitting 50mm Marzocchi's, I'm still undecided whether I should really keep it period correct or just go the easy route and bolt modern stuff to it...... :dunno

I have been doing some searching but I can't find much with google, so I switched to studying pics of old bikes...

The 86 Honda has what looks like a roadbook holder on the 'bars.

But looks to have gone the next year.

1988 Yamaha YZE looks to have an electrically advanced roadbook.

1990 Cagiva

I suggest you look at this beautiful website, plenty of useful images

It looks there were some electrical roadbook holder around '87 and ICO around '89 ?

As I recall seeing them, the original MD Roadrunner goes back to about 1988/89 - prior to that it was a mixed batch of home made/manually driven, bar mounted "boxes" - for the mostpart.

The MD - as shown on the photo's tREV posted of the BYRD Yamaha's and Lucky Strike Cagiva's of the day - was really the first commercially available electric driven roadbook roller (and it's internal rubber o-ring driven design has been largely unchanged since then).

Back in the day the only other readily available (commercially sold) alternative was the venerable Acerbis plastic map holder (white plastic).

Other than that most of the RB' rollers I've seen from back in that period were either individuially fabricated (or very limited hand production line) versions of manual (sometimes el driven) holders usually fabricated in light guage aluminium or stainless steel.

What did your DR BIG have on it back then TT...?

Tony T 11-06-2012 03:41 AM

Thanks folks.
The DR originally had a white plastic, manual Acerbis unit with an old white ICO back in the day.
I've still got one of the old ICO's that came off Mick Goddard's ill-fated KLX and I'm sure there's an MD Roadrunner on an old Husky.
So, maybe it could look reasonably period correct with that combo.

Not that I'm going racing on it (I think............ :wink: ) but I would like to have an electric unit on it.

Currently, it's in a lot of pieces, but here's what it used to look like.
