by Glenn Roberts http://www.motorcyclemojo.com ![]() The day was hot, really hot, as most of the summer has been in Ontario. My plan was to head up north and maybe, just maybe, get some reprieve from the heat. I would be traveling on Ontario's major 400 series highway system and then head back to the office on some cottage country back roads. This way I could get the feel of the R1200RT on the faster, smoother highways as well as the not-so-smooth secondary roads that twist and turn through Ontario's cottage country. Change is good. Change forces other manufacturers to sit up and take notice and possibly follow a trend, or it sets the manufacturer apart from its peers and keeps the product fresh. No one can argue though, that the drive line changes have consistently meant more power in a smoother, lighter and more efficient package and the most current re-design of the 82 year old boxer engine to today's standards is proof of that. The revised counter-balanced, horizontally opposed engine was first seen in the 2004 R1200GS, BMW's big adventure touring motorcycle, in which they shaved a total of 66 pounds off the complete bike while increasing overall performance. No small feat to say the least. Now the 2005 R1200ST and RT models have seen the same type of reduction using the same boxer engine albeit with 10 extra horsepower than the GS model. BMW's new R1200RT has been redefined as a more relaxed touring machine and is a redesigned version of the R1150RT which utilized the previous version of BMW's well known boxer engine. The boxer design dates back to 1923 where it was used in the very first BMW motorcycle. The engine has proven itself time and time again over the years and through various updates along the way is continuing to be a mainstay of BMW Motorrad. The new boxer engine's size has been increased to 1172cc from 1130cc with an increase in output to 110 horsepower at 7,500rpm as well as an increase in torque to 115Nm (85ft/lbs) at 6,000rpm. The new figures represent an increase of 15hp and 15Nm over the previous model boxer. An improved engine electronics and sensor system utilizes a Single Wire CAN-Bus System resulting in more efficient electronic communication between sensors and the Electronic Control Unit as well as realizing some weight reduction because of a lighter smaller wiring harness. To further reduce emissions, a three-way catalytic converter, engine knock sensors and a dual spark ignition system have been employed ensuring efficient combustion. The knock sensors and the dual spark system also prevents the engine from 'pinging' which could damage internal components of the engine. The opposed twin engine implements the use of a counterbalance shaft which keeps the engine vibration to a minimum although at idle the windshield and fairing shook a bit but that was completely eliminated above idle. I did feel a little vibration on acceleration around 4,700rpm in top gear through the handlebars but not enough to be annoying. The torsional twist inherent in the boxer engine while blipping the throttle wasn't as predominant as in previous designs and I was soon oblivious to it. The fuel injection system delivers a crisp throttle response and the engine produces sufficient power from 3,500rpm and up to make for effortless throttle roll-on passing at highway speeds without down-shifting. From a standing start the RT gets to speed quickly and efficiently. Shifting was smooth in every gear and required very little effort on the shift lever. A heavy clunk was noticed, however, shifting from first to second and vise-versa. Finding neutral was consistently easy although sometimes getting into first required letting the clutch lever out in neutral and shifting into first just as the clutch was pulled in. The clutch is a single plate dry disc and is predictably smooth in operation with the hydraulic clutch lever. The front Telelever and rear Paralever suspension utilized on the R1200RT as on many of the BMW line works exceptionally well. The Telelever suspension keeps brake dive to a minimum ensuring the steering geometry stays the same in virtually all situations. The rear single sided swing arm incorporates the shaft drive and the Paralever suspension. The jacking effect, whereby the rear of the motorcycle lifts on acceleration and is common on shaft driven motorcycles, is negligible on the R1200RT. The RT corners with confidence and soaks up the bumps on any type of road regardless of its condition. The rear suspension spring rate is adjustable under the seat. New this year on some BMW motorcycles is Electronic Suspension Adjustment (ESA). ESA is an innovative system that allows the rider to adjust suspension settings on the fly through the touch of a button eliminating complicated manual adjustments. Depending on the type of road surface, the load or the style of riding, the rider can select from Normal, Comfort and Sport settings that previously required the rider to dismount to adjust. Manual adjustment of the suspension settings takes a lot of experience and trial and error to get it right. Now it's just a push of a button away. Unfortunately my demo was not equipped with ESA so I cannot comment on its function but I look forward to trying it in the future. The RT's brakes delivered good brake feel and stopped quickly and efficiently utilizing BMW's well established Integral ABS II system which comes standard on the RT. The hand brake lever applies the power assisted front and rear brakes delivering exceptional braking power while the rear brake pedal only applies the rear brakes as normal. The dual front floating brake rotors are 320mm and are squeezed by 4-piston calipers, the rear brake consists of a 2-piston caliper and a 265mm brake rotor. All flexible brake lines, as well as the clutch line, are steel braided flex lines which definitely helps in the solid feel of the brake system. The transfer of braking power to the road is through cast aluminum wheels and Dunlop Sportmax rubber. The front carries a 120/70ZR17 and on the rear is a 180/55ZR17 tire. One nice feature on the front wheel is the air pressure valve stem. I know from experience how hard it is to get a tire pressure gauge or air chuck between a pair of large brake rotors and cast spokes. The valve stem on my demo model was positioned on the side of one of the spokes making it very easily accessible for an air pressure gauge or air chuck. This simple little modification eliminates that annoyance. The R1200RT has a claimed dry weight of 229kg (504lbs) and a road-ready weight of 259kg (570lbs) but looks like a larger bike because of the expansive fairing. It seemed to dwarf other bikes that were present in its immediate vicinity. Balancing the bike was never an issue due to its low centre of gravity, thanks to the low slung boxer engine and transmission. Putting the RT on its centre stand was a breeze and has to be one of the easiest bikes on the market to do so. With your body weight on the centre stand and a very slight pull on the easy to reach grab handle, the bike moves up onto the centre stand with surprising ease. The RT's dash is well lit and easy to read with a combination of analog dials for the speedometer and tach and a digital flat screen display. The flat screen displays items such as odometer, trip meters A and B, fuel level, oil temperature, selected gear, ambient air temperature, average fuel mileage and ESA settings if the bike is equipped with the ESA option. The flat panel display also provided radio, CD, auxiliary input and intercom information if the optional audio system is installed. The flat panel adjusts to current light conditions making it always easy to read.
Ridiculously high fuel prices during the last third of the year make the RT very appealing. The RT's large fuel tank holds 27 litres and the on-board computer claims over 540kms from a full tank is achievable with 300kms left at a half tank. I averaged 4.7l/100kms (61.5mpg) on the RT and by doing the math the bike should be able to get 586kms from a tank of fuel. That kind of mileage rivals that of today's hybrid cars. My first fuel stop was at 400kms and the bike took 18 litres leaving 9 litres left making for a saddle time of many hours between fuel stops on those long trips. This is of course what the R1200RT was designed for, a long distance touring machine. I did find that after a full days riding with few fuel stops, my rear end was a little tired of being in the saddle. In all fairness to the bike, sitting in one spot for many hours and not being able to move much will contribute to 'numb bum' though. The seat was comfortable and gave good support and is designed so it's not-too-wide in the front section to make it easy to plant your feet flat on the ground. Generally, when riding with friends, fuel and stretch stops will be more frequent depending on riding styles and tank capacities of the other bikes in the group. The riding position is very comfortable. The handlebars come back to meet you allowing the rider to sit straight up and the footpegs are in such a position for the rider to sit in a naturally relaxed position. I found the dual height seat a little high for my 32" inseam but it never was a cause for concern except when trying to back up on uneven ground. The seat has an adjustable height of 820mm and 840mm (32" and 32.75"). For long trips, the higher setting lets your legs stretch a bit more. An optional lower seat is available with a seat height of 780mm and 800mm (30.4" and 31.2"). On one of the days I was out riding, the on-board computer display panel showed an ambient outside temperature of 31o celsius and, as most of the summer has been, the high humidity made it feel more like the high 30's or even 40o. The R1200RT provides excellent rider protection from the elements but this also means protecting you from the cooling breeze on a hot day. As hot as it was though I didn't find it unbearable with the windscreen in its lower position. The power windscreen, activated with a button on the left handlebar, has a total range of 130mm (5") completely eliminating any helmet buffeting and windnoise when in its highest position. Unfortunately I was not able to ride the bike in the rain to get a real feel for the weather protection it provides. The fairing mounted headlights, two low beam and one center high beam, brightly lit the road up during the night's ride. The mirrors, also mounted to the fairing, provide a good view of the road behind and were free of vibration regardless of road or engine speed. All the handle bar controls were easy to reach and operate and the hydraulic clutch and front brake levers are adjustable for different hand sizes. As is standard on many BMW motorcycles are heated grips, definitely a nice touch in the spring and fall. The bike I was riding did not have cruise control installed but it is an available option as is the heated seat. The spacious system cases, or saddlebags, are both of equal size and easily swallowed my full face helmet with room to spare. Inside each case are adjustable straps to secure items and prevent things from falling out while the cases are opened. The side cases are easy to remove with one hand and the bike still looks great with them off. Also available options for the touring minded rider are two sizes of rear top cases which easily attach to the large luggage rack behind the passenger seat and an easily attached tank bag which clips onto a receiver atop the fuel tank. There is also limited room for some storage under the passenger seat. Passenger room is plentiful with a large comfortable seat and rear footpegs that are ergonomically placed for comfort. The optional top case also acts as a back rest for the passenger. A very enjoyable well mannered touring bike capable of virtually any type of riding and able to cover long distances on a single tank of fuel in total comfort. The more things change, the more things stay the same. The re-design of the whole motorcycle has been drastic with the newest version of the boxer engine and the visually striking appearance that will keep these BMW touring bikes in the forefront among long distance riders just as the previous models have been.
