2004 BMW R 1150R Overview
The 2004 BMW R 1150R is a naked bike motorcycle built around 1130 cc of displacement. Under the tank sits a Two cylinder boxer engine running High Camshaft (HC) valve actuation, a compression ratio of 10.3:1. 2004 BMW R 1150R delivers 70 kW @ 7250 rpm of peak power and 98 Nm @ 5500 rpm of torque. The factory-quoted top speed stands at 203.3 km/h, making it a capable performer in its class. From a practical standpoint, the 2004 R 1150R tips the scales at 238 kg, carries a 20.4-litre fuel tank, offers a seat height of 800 mm and spans a 1487 mm wheelbase. That's roughly 37.5 kg heavier than the average naked bike in our database.

2004 R 1150R - Pros & Cons
Strengths
-
⚡
Strong power output: 2004 BMW R 1150R makes 70 kW @ 7250 rpm with 98 Nm @ 5500 rpm of torque - competitive figures for its class.
-
🛑
Strong front braking: The disc front brake gives excellent stopping power and responds well to aftermarket braided lines.
-
⛽
Large fuel range: The 20.4-litre tank is generously sized, translating to extended range between stops - ideal for touring or longer commutes.
-
⚙️
Low-maintenance final drive: Shaft final drive means no chain to clean, lube or adjust - meaningfully less routine maintenance than a chain-driven equivalent.
Considerations
-
ℹ️
Age-related wear: As with any used R 1150R, a thorough pre-purchase inspection covering consumables, service history and tyres is always recommended.
Wear Points & Servicing Notes
Heat management in traffic
R 1150R's air-cooled design means engine-bay temperatures build up more in stop-start traffic than on a liquid-cooled equivalent - a function of the cooling method itself, not a defect. Mesh riding gear and avoiding prolonged idling help in hot climates.
Brake disc and pad wear
The disc front brake gives strong, progressive stopping power. Disc thickness and pad depth are worth checking at every tyre change, since worn pads can score the disc surface.
Suspension condition on used examples
Up front, the R 1150R runs Telelever with central spring strut & linear-rate coil spring. Twin-tube gas-filled shock and Patented BMW Paralever swingarm & shaft drive, single tube gas filled shock, variable rebound setting at the rear. On a used example, check fork seals for weeping oil and test the rear linkage for play - seals are a relatively cheap fix but useful when negotiating price.
Final drive maintenance
Final drive is by shaft - no chain or belt maintenance at all, though the drive-shaft oil should be changed on the manufacturer's interval.
Frame & chassis check
The frame is Three section composite frame consisting of front & rear section, load bearing engine - worth a visual check for corrosion or impact damage around the head-stock and swingarm pivot on any used example, since frame damage is far costlier to fix than any service item.
Handling the weight at a standstill
At 238 kg, the R 1150R is a substantial machine - low-speed manoeuvring in car parks takes more physical effort than on a lighter bike, though the weight disappears once rolling.
R 1150R - Buying & Maintenance Guide
What to check before buying
When inspecting a used 2004 BMW R 1150R with its 1130 cc naked bike, start with the basics: check the service book for oil change frequency, inspect the drivetrain for wear, and look for oil seepage around the engine casings and rocker covers. This model runs shaft final drive, so ask for proof the shaft-drive gear oil has been changed on schedule - it's easy to overlook since there's no chain to draw attention to it. Now 22 years old, this naked bike is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. A cold start test is invaluable - a well-maintained R 1150R should fire up cleanly and settle to a smooth idle within a few seconds.
Oil and filter changes
Regular oil changes are the single most important maintenance task for the R 1150R's 1130 cc two cylinder boxer. Stick to the manufacturer's interval - typically every 6,000 km or once a year, whichever comes first. With a 10.3:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Always use the correct viscosity grade as specified in the owner's manual.
Fuel system care
The R 1150R's fuel injection system is durable but benefits from quality fuel and the occasional use of a fuel-system cleaner additive. If the bike has been stored for more than three months, drain and replace the fuel to prevent varnish deposits in the injectors.
