2001 R 1100S - Pros & Cons
Strengths
-
⚡
Strong power output: 2001 BMW R 1100S makes 71.4 kW @ 7500 rpm with 97 Nm of torque - competitive figures for its class.
-
🔧
Fuel injection: The Bosch fuel injection system delivers crisp throttle response and reliable cold starts regardless of altitude or temperature.
-
⛽
Large fuel range: The 18-litre tank is generously sized, translating to extended range between stops - ideal for touring or longer commutes.
-
⚙️
Low-maintenance final drive: Shaft final drive means no chain to clean, lube or adjust - meaningfully less routine maintenance than a chain-driven equivalent.
Considerations
-
ℹ️
Age-related wear: As with any used R 1100S, a thorough pre-purchase inspection covering consumables, service history and tyres is always recommended.
Wear Points & Servicing Notes
Heat management in traffic
R 1100S's air-cooled design means engine-bay temperatures build up more in stop-start traffic than on a liquid-cooled equivalent - a function of the cooling method itself, not a defect. Mesh riding gear and avoiding prolonged idling help in hot climates.
Fuelling & injector care
Fuelling comes from Bosch fuel injection. Systems like this are largely maintenance-free beyond keeping fuel quality decent and injectors clear - a fuel-system cleaner every service interval is cheap insurance.
Brake disc and pad wear
The 2 x 320mm discs, 4 piston calipers front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.
Suspension condition on used examples
Up front, the R 1100S runs Motorrad Telelever, stanchion diameter 35mm, central strut, rebound damping adjustable and Paralever, central strut, spring preload adjustable to continuously variable levels by mean of a hydraulic handwheel, rebound adjustable damping at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by shaft - no chain or belt maintenance at all, though the drive-shaft oil should be changed on the manufacturer's interval.
Frame & chassis check
The frame is Three section composite frame consisting of front & rear section, load bearing engine - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.
Handling the weight at a standstill
At 236 kg, the R 1100S is a substantial machine - low-speed manoeuvring in car parks takes more physical effort than on a lighter bike, though the weight disappears once rolling.
R 1100S - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2001 BMW R 1100S, start with the basics: check the service book for oil change frequency, inspect the chain and sprockets for wear, and look for oil seepage around the engine casings and rocker covers. A cold start test is invaluable - a well-maintained R 1100S should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task on any R 1100S. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. Always use the correct viscosity grade as specified in the owner's manual.
Fuel system care
The R 1100S's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
