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 42.5 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 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 should cover the same ground every time: service history, chain and sprocket condition, and any oil seepage around the casings. 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 a R 16's engine - keep to the manufacturer's interval rather than stretching it. Use the viscosity grade the manual specifies, not whatever's on sale.

Carburetor upkeep

A 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.
