Hi folks, I am thinking about dipping my toe into the antiques, I much more familiar with the classic airheads. I have the opportunity to purchase this R4 from a good acquaintance, who knows little about it including value. I would appreciate some guidance around this bike, first and foremost, what is something like this worth? It is a non-runner but motor turns over, apparently it fired up 20+ years ago when the current owner purchased it. Numbers seem to reflect an R4 from my research and the fork badge looks authentic. Tank looks very clean. Has been repainted at some point. In any event, I have some concerns:

- I haven't seen any R4's with the telescopic front end.
- the motor stamping looks like original numbers but no BMW logos
- the frame stamping looks like modern numbers and may have been stamped over existing numbers???

Not too worried about all this if I can get it for the right price, what would that be in your opinion?

Thanks,
Scott

I agree that the front forks

I agree that the front forks are wrong for any series R4...should have the leaf spring. A book I have, BMW Motorcycles of the Century, lists a price range from 3500 euros for a bike in poor state and 8000 euros for one in great shape.

Where are you located? Maybe you could talk to Vech at Benchmark Works for some input? Below is a link to a restoration he completed on a Series 1 R4.

R4

Hi,

It appears to be a series 4 R4 - but with an R24/R25 front end. Likely a better ride, but not correct. The rest of the machine looks correct including the unobtainium - ultra rare and expensive Walzentacho Speedometer. Speedo is worth $1000 plus - I paid $2000 for a NOS one. I would say if you can get it for $4k - 5k or so you would be doing well. If you want to make it correct (front end wise) you can get one from a supplier in Germany.

Cool machine.

Jeff

R4

I think Jeff has it right.

The frame number on the stay may have been added. Look on the left side of the frame near the rear axel....usually in front of, and maybe a bit above. I would expect to see a P with the number. These numbers are sometimes filled with paint and hard to see.

Rondels would not have been used, at least not in the early production years.

Interestingly, the frame number seems to be very early production and the engine number is mid-production. BMW can probably advise when it was made and where it was delivered.

My R4 knowledge is too limited to identify which series it is by the equipment, but based on the 12 PS on the head tube badge, it would be a series 1 or 2. Series 3-5 had 14 PS.

Is the engine number stamped on the right side of the base of the cylinder?

Definitely a cool bike! It would be a great project.

Thanks guys, I took the

Thanks guys, I took the plunge.

Unfortunately, it will have to sit for a while, albeit now in my garage, but it appears to be a patient beast Smile!

BTW, I contacted BMW Archive and everything matches up, It is a 1935 series 4 and was delivered to a dealer in Leipzig.

Cheers,
Scott
