1989 BMW R 65 Overview

BMW R 65 is a touring motorcycle, displacing 649 cc. Power comes from a Two cylinder boxer engine running OHV valve actuation, a compression ratio of 8.4:1. Bore and stroke come in at 82 x 61.5 mm. On the performance side, it delivers. Top speed is factory-quoted at 147 km/h. On the road, the 1989 R 65 tips the scales at 205 kg and carries a 22-litre fuel tank. That's roughly 119.1 kg lighter than the average touring motorcycle in our database. The full 1989 BMW R 65 spec sheet below covers every technical detail, from suspension travel to tyre sizes.

1989 R 65 - Pros & Cons

Strengths

Large fuel range: A 22-litre tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.
Low-maintenance final drive: Running Shaft drive (cardan) final drive cuts out the regular chain cleaning and tensioning that most bikes need.

Considerations

Age-related wear: Nothing specific stands out as a weak point on the R 65 - the usual used-bike checks (service history, consumables, tyres) apply.

Wear Points & Servicing Notes

Brake disc and pad wear

Braking up front comes from Single disc - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.

Final drive maintenance

The R 65 uses shaft final drive: essentially maintenance-free day to day, with periodic gear-oil changes the only real service item.

R 65 - Buying & Maintenance Guide

What to check before buying

Before handing over money for a used 1989 BMW R 65, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy R 65 should catch quickly and settle into a smooth idle.

Oil and filter changes

Nothing protects a R 65's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
