Other Bikes » 1978 R100RS v 2019 R1250RS

I admit that I may be less carefree now than before my "off" in July. If so, I really can't measure it except under very heavy braking when my left shoulder protests. In any event, I am astonished by the great increase in acceleration between the R1200 RS and the R1250 RS. I seldom used full power with the 1200. I can't see where I can use full power on the 1250 - at least without a HUGE risk of finding myself at the wrong end of a policeman's pen.

So, I was thinking back on my early years of riding (1968) and then to the earliest version of the BMW RS, namely the 1978 R100 RS and thought I would compare the two models to see what has happened over the years.

Because the table is "structured" I don't seem to be able to just "cut and paste" into the message so I am attempting to attach it.

Looking at the numbers, just imagine how much materials engineering, electronic engineering, machining and the like has gone into a bike that ONLY 43 years later (oh I do feel old) weighs 13 kg more, has double the horsepower and double the torque, has brakes that threaten to tenderise your lower regions when applied with vigour, and has ABS, Traction Control, Cruise Control, hugely improved lights, hugely improved ignition and fuelling systems, better managed suspension, a much better gearbox and final drive. I haven't even started on the information provided to the rider (bike readings, music, GPS, telephone), or small easily overlooked things like the hydraulic steering damper and easily accessible air line connections to the tyres. Maybe the aero package on the R100RS was better, but I have not seen later bikes adopt the enclosure around the forks attached to the lower fairing.

Were it not for the corporate fear of headlines that "XXXX Manufactures Killer Bikes" maybe someone would publish verifiable acceleration and top speed data - but that is probably a bridge too far.

I like the bigger fuel tank on the R100RS

I recently resurrected my '85 K100/1100RS from a year's slumber and have been riding it locally. I just can't get over the fact that I rode it for over 300,000 miles and loved it. Compared to my other two bikes ('17 R1200RS and '03 R1100S/BCR), it doesn't go, stop, handle or ride worth a damn. Once you've been exposed to modern bikes, the old ones just don't do it any longer.

I want the R100RS tank size with the R1200RS fuel mileage.

Apart from the differences in physical size, weight and power, there are also significant differences in the information given to the rider, and the operation of the bike. From memory, common, and useful, feature of the two are:
Shaft drive
Centre Stand
Electric Start
Turn indicators
And the R100RS had (again from memory) tyre repair kit (and space under the saddle) and a pump.

If the R100RS was to be fitted with the following features (many of which were just not technically possible in 1978), imagine its weight, size and the physical complexity of the "analogue" equivalent:

1) Wheels
a. One piece cast wheels
b. Quick detach rear wheel (leaving drive and brakes in place)
c. Radial ply tyres
d. Tyre Pressure Monitor
e. Tyre valve in cast spoke
2) Brakes
a. ABS (with variable settings)
b. Braided steel brake lines
c. Brake pads can be removed / replaced without removing calipers
d. Cornering ABS
e. Hill Assist holding brakes
f. Linked front and rearbrakes, unlinked rear brake.
g. Radial 4 piston Brembos (front)
h. Sliding calliper 2 piston Brembo (rear),
3) Suspension
a. ESA suspension
b. Hydraulic steering damper
c. Upside down forks
d. Weight sensitive, self leveling rear suspension
4) Minor controls
a. Electronic throttle
b. Hydraulic brakes
c. Hydraulic Clutch
5) Rider Information
a. Ambient temperature display
b. Fuel economy display
c. Fuel gauge
d. Gear position indicator
e. Klms / Miles to empty display
f. Low fuel warning light
g. Motor temperature display
h. Oil level monitor
i. Overall fault monitoring and warning for ABS system, Traction Control system.
j. Service reminder
k. Static battery charge / digital battery meter
l. Tyre presssure reading and monitor
m. Upshift indictor (whoopee)
6) Chassis
a. Side Stand deployed engine cut-off
b. Single sided swing arm
c. Standard integrated Pannier mounts
d. Standard integrated Top Box mount
7) Exhaust
a. Power valve exhaust.
b. Stainless steel headers
8) Lighting
a. Dual LED headlights
b. Dynamic pulsing brake light
c. LED brake light
d. LED front DLRs
e. LED turn signals
9) Rider Assistance
a. Accessory power socket
b. Adjustable foot controls
c. Automatic clock setting (with Nav V / VI GPS)
d. Automatic Daylight Running Lights
e. Automatic headlights
f. Cruise control
g. Electronic keyless steering lock
h. Electronically locked petrol cap
i. Fuel gauge
j. Hazard flashers
k. Heated hand grips
l. Inbuilt Bluetooth music (with own phone)
m. Inbuilt GPS (with own phone)
n. integrated Bluetooth music (with Nav V / VI GPS)
o. Integrated GPS
p. Integrated GPS (with Nav V / VI GPS)
q. Keyless ride
r. Night time courtesy lights
s. Quick shifter, up and down
t. Self cancelling indicators
u. Span adjustable span hand levers
v. Switchable Traction control
w. TFT instruments with diagnostics and reporting
10) Motor features
a. 4 valve heads
b. Coil on plug ignition
c. Counter balancer
d. DOHC motor with 4 valves
e. EFI
f. Engine mode selectors
g. Liquid cooling
h. OBD-II Diagonistic Port
i. Shift cam technology
j. Shim on valve valve lash adjustment
k. Slipper clutch

And 40 years later there are a lot of 1000RSs still in regular use. Anybody care to have a guess how many of our RSs will be around for that long?

It's interesting the weight has not gone up much.
R100RS 507 pounds
R1200RS 520 pounds
R1250RS 536 pounds

Here are my "pair"
1981 R100RS with Cruise control ( a friction screw under the throttle grip) !!
2016 R1200RS
