1929 BMW R 16 Overview

For 1929, BMW offers the R 16 as an all-round motorcycle with 735 cc on tap. The 1929 BMW R 16 is built around a Four stroke, two cylinder flat twin, OHV, 2 valves per cylinder engine, a compression ratio of 6.75:1. Out on the road, the R 16 delivers 18.6 kW @ 4000 rpm of peak power. In everyday use, the 1929 R 16 tips the scales at 165 kg and carries a 14 L fuel tank. That's roughly 24 kg lighter than the average all-round motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 1929 BMW R 16 spec sheet below.

1929 BMW R 16 compared with other bikes in the All-Round category

Measured against other bikes in the All-Round category in our database (up to 381 models, one entry per model), the 1929 BMW R 16 comes out as follows.

  • With 165 kg, the R 16 has the joint 118th lightest wet weight of 381 bikes in the All-Round category, 13% below the category average of 189 kg.
  • Power output of 18.6 kW is lower than that of 94 of the other 145 bikes in the All-Round category.
  • Narrowing the field to the 11 models within five model years of it, the wet weight of 165 kg is lighter than that of 3 of the other 10.

1929 R 16 - Pros & Cons

Strengths

  • Capable power output: 18.6 kW @ 4000 rpm of peak output puts the R 16 in good company among its rivals.
  • Low-maintenance final drive: Shaft final drive is about as close to maintenance-free as motorcycle drivetrains get.

Considerations

  • Carburetor fuelling: Carburetion is more hands-on than fuel injection - plan on periodic jetting and cleaning as part of routine ownership.

Wear Points & Servicing Notes

Heat management in traffic

Air cooling on the R 16 keeps the mechanical layout simple, but heat management in slow traffic needs more attention than on a liquid-cooled bike - plan routes and gear accordingly in warmer conditions.

Carburetor maintenance

Being carbureted, the R 16 is more sensitive to stale fuel and altitude changes than a fuel-injected bike - a carb clean and rejet restores crisp throttle response after any extended lay-up.

Suspension condition on used examples

Suspension duties are handled by Plate spring, 9 laminae up front and Rigid, spring loaded saddle at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Final drive maintenance

Shaft final drive on the R 16 removes chain and belt maintenance entirely - the trade-off is a little extra unsprung weight and periodic gear-oil changes.

Frame & chassis check

The Twin loop pressed steel frame chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.

R 16 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 1929 BMW R 16 with its 735 cc all-round should cover the same ground every time: service history, drivetrain condition, and any oil seepage around the casings. This model runs shaft final drive, so ask for proof the shaft-drive gear oil has been changed on schedule - it's easy to overlook since there's no chain to draw attention to it. Now 97 years old, this all-round is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept R 16 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for the R 16's 735 cc four stroke, two cylinder flat twin, ohv, 2 valves per cylinder. - keep to the manufacturer's interval rather than stretching it. With a 6.75:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.

Carburetor upkeep

An R 16 that's sat unused is almost always a carb-cleaning job before it runs right again - float bowls and pilot jets first, since they clog before anything else.
