1978 Moto Grand Record - Anybody have one?

Hey all:

There's a '78 Grand Record at a good price on my local CL. I've been looking for a "go fast" bike to augment the 82 Grand Jubile I'm riding now, and I'm tempted to go get this one. A few questions:

My Grand Record has a full Vitus 172 frame and fork, a nice ride but kinda porky at around 25 lbs. The 78 GR has full Vitus 172 as well, and the 78 catalog lists its weight at 24 lbs, even though the 79 Grand Record with ostensibly the same frame is listed at 22 lbs. What gives?

I'm assuming the geometry would be "racier" than my Grand Jubile, which is pretty laid back, but the catalogs from that era don't mention the frame angles.

I'd be happy to get any feedback on how the 78 Grand Record (or any of the Vitus Grand Records) ride, just wondering if this would be a minor upgrade or a lateral move? I've always loved Motos, and might go for it anyway just to start a collection; the 78 Grand Record sports Motobecane's "new" styling, and I've always liked it - but what I'm really looking for is a different kind of ride.

Should the above, highlighted word be Jubile?

If it is the Westchester GR, I am pretty sure it is a non-original fork, and hence it is overpriced IMHO. I believe the GR frame geometry is set up with shorter wheelbase and the fork angle is steeper, thus more nimble than the GJ.

My '78 Team Champion (Columbus SL) is about 21.5 lbs with tubulars. I'm not sure I would trust that 22 # claim.

my '76 g.record is 531 with heavier rear stays.

the '80 g.jubilé i had was full vitus 172 and a good two inches longer in wheelbase in comparison. it didn't feel heavy at all. after owning that bike, i've wanted to find a racier geometry with the same underrated tubing.

the vitus g.records are a tough sell at premium prices. there was a really nice one on ebay not long ago for under $400 shipped. so, with that in mind, and if the price is right, buy it to ride (not flip).

Whoops! Yes, meant Jubile...

No, it's not the one in Westchester, that bike is too rich for my blood and I noticed the replacement fork as well. The one I'm eyeing is in Long Island, has the "new" styling rather than the "classic" styling.

Different components.. 78 has the SunTour, Weinman, SR, Maillard mixed group. The 79 has a Shimano 600EX group.

Catalog weight + pedals + whatever = add 2 or three pounds. Catalog weights are [strike]bull****[/strike] advertising.

Vitus 172 tubing had the same wall thicknesses as the Reynolds 531 tubes used on most French production frames.

The main tubes were 1.0mm thick in the butted sections and 0.7mm thick throughout the rest of the tubes. Forks, seat and chain stays were about the same too. That was the same as Columbus SP tubing.

Vitus 172 tubing had about 90-95% of the strength as Reynolds 531 or Columbus SL or SP. The tubing used the same forks as Super Vitus 971 tubing.

BTW, only the top and down tubes were double butted on a "double butted frame":



The ride should be the same as a Reynolds 531 frame with identical dimensions and geometry.

The average weight for a bike like the the Grand Record is about 24 to 25 Lbs. with clinchers and alloy rims depending on frame size. With sewups it would weigh ~22 to 23 Lbs.

1978 Motobecane US Catalog - Grand Record page with specs.
