That's roughly 17.5 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 1954 BMW R 68 spec sheet below.

1954 R 68 - Pros & Cons

Strengths

Capable power output: 26.1 kW @ 7000 rpm of peak output puts the R 68 in good company among its rivals.

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 68 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 68 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 Telescopic front fork with hydraulic damping; plunger type up front and Spring with coil compression springs and rubber deflection stops at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.

Frame & chassis check

The Double loop steel tubular 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 68 - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 1954 BMW R 68 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 68 settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for a R 68'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 68 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.
