The '''BMW R1100RSR1100S''' is a [[sport bike|sports]] [[motorcycle]] that was manufactured by [[BMW Motorrad]] between 19991998 and 2005. Introduced some 25 years after the [[BMW R90S|R90S]], the company's first sports bike, the R1100S was the first BMW bike having [[Motorcycle handlebar#Types of handlebarhandlebars|clip-on handlebars]], rearset footrests and a removable cowl to cover the pillion seat.<ref name=bmwhistory/> Producing nearly 100 &nbsp;hp, it has been described as a "sporty [[Sport touring motorcycle|sports-tourer]]".<ref name="Motorcycle20Oct98">{{cite news|url = https://www.motorcycle.com/manufacturer/bmw/first-ride-1999-bmw-r1100s-1425.html|title = First Ride: 1999 BMW R1100S|accessdateaccess-date = 29 December 2014|last = MO Staff |date = 20 October 1998| work = Motorcycle.com}}</ref>
 
==Design==
The engine is a [[flat-twin engine|flat-twin]] "[[History of BMW motorcycles#Oilheads|"oilhead"]]" that has [[air cooling|air-cooled]] cylinders but [[oil cooling|oil-cooled heads]]. Derived from the [[BMW R1100RS]], the 1,085&nbsp;cc [[Fuel injection|fuel-injected]] [[Multi-valve|eight-valve]] engine is tuned for a maximum output of {{convert|98|hp|kW|}} at 8,400rpm.<ref>http: name="Motorcycle20Oct98"//www.bmbikes.co.uk/PDF%20Downloads/R1100SSpec.pdf</ref><ref name="Motorcycle20Oct98bmbikes.co.uk"/> At the time of its introduction, it was BMW's most powerful boxer engine ever made, and the first mated to a six-speed transmission.<ref>{{citation|title=2007 BMW R1200S Road Test |journal=Rider |date=January 26, 2007 |url=http://www.ridermagazine.com/road-tests/2007-bmw-r1200s-road-test.htm/ |url-status=dead|archive-url=https://web.archive.org/web/20141230223146/http://www.ridermagazine.com/road-tests/2007-bmw-r1200s-road-test.htm/ |archive-date=2014-12-30 }}</ref> The [[Overhead valve#Developments|ohv]] engine has chain-driven camshafts mounted in the cylinder heads, operating the valves ''via'' short pushrods and rocker arms.

In addition to using the engine as a [[Motorcycle frame#Stressed member|stressed member]], the R1100S has a composite aluminum frame to which the suspension components are attached. The front suspension is BMW's [[patent]]ed [[History of BMW motorcycles#Telelever fork|Telelever]], with long [[telescopic fork|telescopic fork sliders]] containing neither springs nor damping. In order to minimize [[Suspension (motorcycle)#Brake dive|"fork dive"]], braking forces are taken back to the frame ''via'' a pivoting wishbone. A [[monoshock]] on this wishbone copes with springing and damping. <ref>{{cite web|url=http://www.dinamoto.it/dinamoto/8_on-line_papers/Telelever%20or%20forks/Telelever_eng.html|title=BMW Telelever and telescopic forks: which is better? |publisher=dinamoto.it|accessdateaccess-date=29 December 2014|archive-url=https://web.archive.org/web/20100516043608/http://www.dinamoto.it/dinamoto/8_on-line_papers/Telelever%20or%20forks/Telelever.html|archive-date=16 May 2010|url-status=dead}}</ref><ref>{{cite web|url=http://www.motorbikestoday.com/features/Articles/bmw_telelever.htm|title=BMW Telelever Explained|publisher=Motorbikes Today|accessdateaccess-date=29 December 2014}}</ref> The rear suspension comprises BMW's "[[History of BMW motorcycles#Paralever|Paralever]]", a [[Swingarm#single-sided swingarm|single-sided swinging arm]] encompassing [[shaft drive#Motorcycle drive shafts|shaft drive]].<ref name="motorbikestoday">{{cite web|url=http://www.motorbikestoday.com/reviews/Articles/bmw_r1100s_03.htm|title=BMW R1100S Road test|publisher=motorbikestoday.com|accessdateaccess-date=21 December 2014}}</ref> The Paralever mounts directly to the frame instead of to the gearbox as on earlier oilheads.

A detachable tubular [[subframe]] supports the rider and passenger. The R1100S has a very substantial half fairing, andwhich bothcompletely envelops the alloy fuel tank. Both the hugger (after market option) and front fender are made of carbon-fibre. The two-into-one exhaust feeds twin silencers tucked up high underbeneath the pillion seat, like those on the [[Ducati 916]].<ref name=what2004/> Factory options originally available from BMW included electrically- heated grips, [[Anti-lock braking system|ABS]] brakes and a belly-pan fairing.<ref name="motorbikestoday"/>
 
==Reception==▼
==Special editions of the BMW R1100S==▼
The R1100S is {{convert|27|kg|abbr=on}} lighter and {{convert|8|hp|kW|abbr=on}} more powerful than the [[BMW R1100RS]] from which it was derived, but at {{convert|229|kg|abbr=on}} (wet), it is still no lightweight. Nevertheless, ''What Bike?'' magazine stated: "With underseat exhaust and plenty of ground clearance, the BMW is helped by the lack of dive under braking and makes up metres on the entry to corners. Mid-corner speed is superb, but it's on the exit that the air-cooled twin shows its short legs. Stick to the road, though, and the R1100S is a great place to be".<ref name=what2004>{{citation|journal=What Bike?|date=Summer 2004|publisher=[[Bauer Media]]}}</ref>▼
A special edition model was the '''R1100S Sport''', which was a standard R1100S fitted with an optional "Sport" pack comprising a wider rear wheel and a raised rear suspension (using a longer rear-brake torque arm).
 
''[[Motor Cycle News]]'' (''MCN'') later reviewed the R1100S, stating: "The BMW R1100S is now starting to be regarded as something of a classic, especially in BoxerCup form. Classy styling, [[Honda VF and VFR|VFR]]-esque comfort and versatility plus BMW quality and residuals make for a stonking and attractive all-rounder, if not quite the sports bike BM intended…".<ref>{{cite web|url=http://www.motorcyclenews.com/bike-reviews/bmw/r1100s/1999/|title=BMW R1100S (1999-2005) Review|publisher=MCN}}</ref>▼
A more expensive track-day version of the BMW R1100S, the '''BoxerCup Replika''', was available from 2003-2005. This had uprated [[Öhlins]] suspension, a modified engine management chip, sticky tyres, Laser exhaust, carbon-fibre cylinder head protectors and a bellypan.<ref>{{cite web|url=http://www.visordown.com/reviews/motorcycles/sportsbikes/bmw-r1100s-boxercup-replika-2003---2005/35.html|title=BMW R1100S BoxerCup Replika (2003 - 2005)|work=Visordown|accessdate=21 December 2014}}</ref> The BoxerCup and later Sport models had the engine painted matt black (with the exception of the cylinders and cylinder heads, which remained silver).▼
 
▲==Special editions of the BMW R1100S==
Neither the Replika nor the Sport had a power increase over the standard R1100S.<ref name=what2004/> The BMW factory setting for the electronic fuel injection was extremely lean, but any R1100S can have its digital fuel management remapped to provide a broader spread of torque.

A special edition model was the '''R1100S Sport''', which was a standard R1100S fitted with an optional "Sport" pack comprising stiffer suspension ''via'' a taller rear monoshock, a steering damper, and a wider rear wheel and tyre.<ref>Haynes Manual - "BMW 850,1100 & 1150 4-valve twins" page 0.9</ref> ''Bike'' magazine commented: "The basic R1100S is good value, but we're not convinced that the high spec Sport version offers any real benefit for road riders".<ref>''Bike'' magazine July 2002 page 51</ref>

The raised suspension of the BCR increased cylinder head cornering clearance (compared to the standard R1100RS), but this somewhat compromised the motorcycle for normal town/road use.
▲''[[Motor Cycle News]]'' (''MCN'') later reviewed the R1100S, stating: "The BMW R1100S is now starting to be regarded as something of a classic, especially in BoxerCup form.

The BCR came with a standard engine management chip which was changed for a modified chip at the first dealer service. Despite the different chip, the Replika claimed no more power than the standard R1100S nor the Sport.<ref name=what2004/>
 
==The R1200S==
{{main|BMW R1200S}}
 
The R1100S was eventually superseded in 2006 by the outwardly similar [[BMW R1200S|'''R1200S''']]. The alloy frame of 2006–2007the R1100S was replaced by a lightweight tubular trellis and so, whichwith a tuned engine, the R1200S was {{convert|13|kg|abbr=on}} lighter and 25% more powerful. ''MCN'' compared the R1200S to its predecessor this way: "As an oddball track motorcycle it works, but as an accomplished all-rounder it falls short of the standards set by the R1100S that preceded it."<ref name=MCN2006>[http://www.motorcyclenews.com/bike-reviews/bmw/r1200s/2006/ BMW R1200S (2006-2007) Review], motorcyclenews.com, dated 23 November 2006, retrieved 1 December 2014</ref>
 
In 2008 the R1200S was itself superseded by the [[double overhead camshaft]] [[BMW HP2 Sport|'''HP2 Sport''']].<ref>{{Cite web|url=http://www.topspeed.com/motorcycles/motorcycle-reviews/bmw/2012-bmw-hp2-sport-ar126981.html|title = 2012 BMW HP2 Sport @ Top Speed|date = 26 March 2012}}</ref>
