Analysis
What Problems Does the 1999 BMW R1100RT Have?
Another area to watch is the final drive unit. While not as universally problematic as some later BMW models, occasional failures involving bearings or seals have been reported. Regular fluid changes are crucial here. The clutch splines are another potential, though rarer, catastrophic failure point. If lubrication is neglected or if the transmission input shaft develops excessive play, the splines can wear, leading to clutch slippage or complete failure. This is a labor-intensive and expensive repair.
Electrical gremlins can also appear with age. Brittle wiring, failing relays, or corroded connections can cause intermittent issues with instruments, lights, or heated grips. The plastic quick-disconnect fittings for the fuel lines can also become brittle and crack, potentially leading to fuel leaks; many owners replace these with metal alternatives. Additionally, the rubber components, such as throttle body intake rubbers, fuel lines, and brake lines, will naturally degrade over time and require inspection and replacement. Owners should also check for fluid leaks from the engine (valve cover gaskets) and transmission seals. Recalls for this specific model year are generally minimal, but always consult NHTSA records for any outstanding safety campaigns. Overall, these are durable machines, but age brings its inevitable challenges.

What Technology & Safety Features are Included?
In terms of entertainment, many R1100RT models came equipped with an optional integrated radio system, often with a cassette or CD player, and sometimes an intercom system for rider and passenger communication. This was a relatively luxurious addition for a motorcycle of that era, providing background music or news during extensive tours.
Driver-assistance features as we understand them today (e.g., adaptive cruise control, lane-keeping assist) were nonexistent for motorcycles in 1999. The focus was on fundamental ride stability and rider control.
Safety features were a strong point. The most significant was the optional BMW Integral ABS (Anti-lock Braking System). This advanced system for its time significantly enhanced braking safety, especially in adverse conditions, by preventing wheel lock-up. The powerful dual front and single rear disc brakes provided strong stopping power. The Telelever and Paralever suspension systems contributed to exceptional stability and predictable handling, reducing dive under braking and squat under acceleration. Furthermore, its large, bright headlights and tail lights improved visibility, and the full fairing offered substantial protection from weather and minor road debris. Crash-test ratings are generally not applicable or performed for motorcycles in the same way as passenger cars, so no official ratings exist for the 1999 BMW R1100RT.

Depreciation was steep in its early years, but has now largely flattened out. Factors heavily affecting current resale value include the overall cosmetic and mechanical condition, the completeness of service records, and crucially, whether the optional ABS system is fully functional. A non-working ABS unit significantly devalues the bike due to costly repair estimates. Desirable options like heated grips or a functional radio also add minor value. Ultimately, for a bike of this age, condition and documented maintenance are far more important than raw mileage.

How Does the 1999 BMW R1100RT Compare to Other Motorcycle?
In terms of performance, the R1100RT's 90 hp Boxer engine offered a distinct character, with strong low-to-mid range torque and a smooth power delivery. The Honda ST1100, with its V4 engine, typically offered more horsepower (around 100 hp) and a smoother, higher-revving experience. The Kawasaki Concours 1000, while sportier, had a less refined inline-four engine. The Harley, with its traditional V-twin, focused more on torque at lower RPMs and a different riding sensation entirely.
For features, the R1100RT was arguably class-leading. Its optional ABS, electronically adjustable windscreen, Telelever/Paralever suspension, and integrated hard luggage were cutting-edge for the time. The Honda ST1100 also offered ABS as an option and was known for its excellent wind protection, but the BMW's suspension was more sophisticated. The Concours was generally more basic in its standard equipment.
Reliability was a strong suit for all these touring bikes. The R1100RT's Boxer engine and shaft drive are legendary for longevity, rivalling the bulletproof reputation of the ST1100. Both are considered highly reliable machines if maintained. The Concours was also reliable but perhaps a bit less refined in its overall build.
In terms of price, the BMW was at the premium end when new, comparable to the Honda ST1100. Today, all three offer excellent value on the used market.
Similar Alternatives:
- Honda ST1100 Pan European: A formidable rival, offering comparable comfort, slightly more power, and legendary Honda reliability. A great alternative if you prefer a V4 engine and a slightly more conventional front fork feel.
- Kawasaki Concours 1000 (GTR1000): A sportier, more budget-friendly option. Less refined than the BMW or Honda but still a capable tourer with good reliability.
- Moto Guzzi California (older models): Offers a V-twin boxer-like engine layout and distinct Italian charm, for those seeking a more characterful, less common alternative.
Final Verdict: Is the 1999 BMW R1100RT a Good Motorcycle?
Is it worth buying? Absolutely, but only as a used vehicle and under specific conditions. Look for examples with comprehensive service records, ideally showing regular maintenance. Crucially, verify the functionality of the optional ABS system; if it's faulty, factor in the bypass cost or walk away, as repair is prohibitive. Focus on models with desirable options like heated grips. It's a fantastic value for its touring capabilities and durability, making it an excellent choice for riders who are prepared for potential age-related maintenance, or for those who enjoy DIY wrenching. For the rider who values comfort, stability, and character over raw horsepower, the R1100RT remains a highly recommended, economical long-term touring companion.
