Good day,

This bike is for sale in Germany: http://www.ebay.de/itm/321659102618?_trksid=p2055119.m1438.l2648&ssPageN....

Any thoughts about this bike/seller? How difficult is it to import an antique bike without papers? Any advise is greatly appreciated.

Thank you,

Marc

The price is a good one for

The price is a good one for an authentic bike. An R47 sold last month at the Mecum Las Vegas Auction for almost $90,000. The bike is being sold by Koni Jankowski, who is a well known supplier of repop parts for prewar bikes. He has had it up on Facebook, too.

The pictures look nice. I see a lot of modern repop parts on the bike, which is not a sin in my eyes. Things like the brake and clutch levers, the headlight, the petcock, possibly the carb, the speedo, and some of the hardware. There's a lot of chrome on the bike that should actually be nickel plate. The wheels are the smaller drop center safety rims - a plus in my mind because of the danger of riding on clincher tires - but they are standard 19" wheels and don't match the arc of the fenders perfectly (the clinchers were 22" wheels, I think).

The most glaring fault is that it appears that someone has installed an R11 leaf spring for the front suspension (7 leaves, rather than the 5 that were on the R42/R47 or 6 on the R52-R63 models). This is why the front wheel is pushed so far down from the fender. I bet it doesn't ride too well like that.

Only by sending in the frame and serial number to BMW will you know if this is a real R47 or an R42 that has been gussied up with modern cylinders and heads, and whether the engine and frame left the factory together.

R47 for sale

Hi Darryl,

Thank you for the information on this R47. I had already contacted the BMW Classic Archive last week and they said, they would need close-up pictures of the frame and engine numbers due to an increase of R47 copies on the market. Will see what the result is going to be. My customer is not afraid of paying a healthy price. But the bike needs to match it's history!

Thanks again,

Marc

I've been told that sometime

I've been told that sometime during the production of the R42 they switched from clinchers to 19" drop center rims. Is there a known date when the factory made the switch or was it an option for a period of time or not at all on the R42?

I am pretty certain that BMW

I am pretty certain that BMW changed from clinchers to drop center rims during the R42/R47 generation. I don't know when exactly. For those into this sort of trivia, it was during the R11/R16 generation that BMW started mounting the rims with the 5 "dents" across the drop center, opposite from the valve. These dents keep a tire from coming off the rim much better. Again, I don't know exactly when the change occurred.

Personally, I would change to the drop center rims on any bike I owned, because I ride them and I knew a guy who died when the clincher he was riding on popped and the tire came off the rim instantly and locked his front wheel, throwing him to the ground. I would store the rims for history's sake, of course.

Clinchers

I have ridden well over 5k miles on clinchers and have had a couple of tube failures on the rear wheel. How I kept from crashing I'll never know. Probably because it was on the rear and I was able steer the bike. I am inclined to agree with Darryl that if you want to ride the bike, switch to drop center rims.
If you must use clincher tires,check the tire pressure before every ride and keep it at 50-55psi [or higher if the supplier reccommends]. I also use a dirt bike thorn proof tube. If you can't get the right size at least use a natural rubber tube. I have had the plastic/rubber tubes split after the first air up. Natural rubber tubes will slowly lose air after a while so check the air pressure often. I hope I didn't get to far off subject here, just don't want to hear of some one getting hurt or worse. Ride Smart.
