2005 BMW R1100S Sport
The BMW R1100 S is much more than the sum of its parts. It is a sports motorcycle that dares to be different. It has that indefinable something - "something" that has attracted the world's most respected riders and "something" that inspired the popular and spectacular International BoxerCup race series. Essentially though, the R1100 S is a BMW in the honoured tradition - a quality motorcycle built uncompromisingly for the road - but with true sports capability.
A RRP of £8,010 on the road also makes the R1100 S excellent value for money.
The four valves per cylinder, air/oil-cooled horizontal twin is one of the most powerful production boxer engine in BMW's history. The high-compression four-valve boxer engine features optimised air intake, forged pistons and the latest generation of digital engine electronics. It also has magnesium cylinder heads for reduced weight. The engine develops a punchy 98bhp (72kw) and an equally impressive 97Nm of torque at 5,750 rpm.
Power from the engine is transmitted to the road through a new, close-ratio six-speed gearbox and BMW's ultra-reliable drive shaft. Light, precise gearshift action and extremely well chosen ratios mean that abundant pulling power is available to the rider under all road and traffic situations.
Visually, the R1100 S engine is slightly different to the other power units in BMW's R-range. The bolts on the magnesium cylinder heads are new and there are three protruding fins on the lower half of the head. The word "Magnesium" is inscribed on both rocker covers.
Road and track
Despite the R1100 S's undoubted track capabilities most owners will only ever ride the S on the road. The bike's strength is its sports touring practicality and versatility over other machines of the sports genre.
Unlike many hybrid sport motorcycles the S handles as superbly off the track as it does on. Telelever, the most significant advance in front wheel suspension of the last decade, and other dedicated components, enable the R1100 S to continue the BMW tradition of producing motorcycles with unsurpassed road holding.
Increasing the power output of the new R1100 S also meant upgrading an already good braking system. The new EVO front brake is a significant advance in motorcycle brake technology and by fitting it as standard to the R1100 S, BMW has fulfilled a commitment to produce the safest sports motorcycle available.
Servo-assisted EVO front braking requires approximately half the manual pressure to achieve the same stopping power as a conventional system. Braking is further improved by equipping the R1100 S with two larger front discs (320mm/12.6 inches) and sintered brake pads. This combination produces an increase in braking forces of between 15 and 20 per cent.
The intelligent, third generation integral ABS system is an after-market option that perfectly compliments the new EVO system and is unique to the sport genre.
Riding for real
The R1100 S is a sports motorcycle that will enable its rider to undertake any, on the road, two-wheel task with confidence. The S makes few compromises in the roles it can assume, irrespective of extremes or whether this means commuting, or touring.
The tractability of the R1100 S in town is matched by its adaptability on a long run. An 18-litre tank (of which 4 litres are "reserve") means that the S can achieve a practical touring range approaching 200 miles, depending on the type of riding.
To enhance the sports-touring capabilities of the R1100 S, BMW has provided a number of general and touring options. These include pannier case holders and the spacious BMW system cases, heated grips, raised handlebars and high windscreen.
A sports pack is available for the R1100 S making the model more like a race replica than a road going sportsbike. The sports pack includes sports suspension, 5.5-inch rear rim with an 180 section tyre and white indicator lenses. The pack costs just £475.
