2008 BMW F 800S Overview
For 2008, BMW offers the F 800S as a sport motorcycle with 798 cc on tap. The 2008 BMW F 800S is built around a Liquid-cooled parallel twin, DOHC, 4 valves per cylinder engine, a compression ratio of 12.0:1. Out on the road, the F 800S delivers 62.5 kW @ 8000 rpm of peak power and 80 Nm @ 5800 rpm of torque. Flat out, it's quoted at 219.7 km/h. In everyday use, the 2008 F 800S tips the scales at 209 kg, carries a 16-litre fuel tank, offers a seat height of 820 mm and spans a 1466 mm wheelbase. That's roughly 14.4 kg heavier than the average sport motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 2008 BMW F 800S spec sheet below.
2008 BMW F 800S compared with other bikes in the Sport category
Measured against other bikes in the Sport category in our database (up to 1607 models, one entry per model), the 2008 BMW F 800S comes out as follows.
- With 820 mm, the F 800S has the joint 411th tallest seat height of 1607 bikes in the Sport category.
- Wet weight of 209 kg is heavier than that of 833 of the other 1212 bikes in the Sport category.
- Narrowing the field to the 625 models within five model years of it, the seat height of 820 mm is taller than that of 395 of the other 624.
Versus the 2007 model
The figures we track are unchanged from the 2007 model: peak power, peak torque, wet weight, displacement, seat height and top speed all match.
2008 F 800S - Pros & Cons
Strengths
-
⚡
Strong power output: Peak output on the F 800S is 62.5 kW @ 8000 rpm and 80 Nm @ 5800 rpm of torque - strong numbers for what it is.
-
🔧
Fuel injection: No choke, no jetting, no altitude compensation to think about - fuel injection just works across a wider range of conditions than carburetion.
-
🛑
Strong front braking: The disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.
-
⚙️
Low-maintenance final drive: Belt final drive is about as close to maintenance-free as motorcycle drivetrains get.
Considerations
-
📏
Tall seat height: An 820 mm seat puts flat-footing out of reach for a lot of riders - sit on it in person before committing.
Wear Points & Servicing Notes
Cooling system servicing
With Liquid cooled, thermal management is largely automatic, but the coolant has a service life of its own - replace it on the manufacturer's interval to protect the water passages and thermostat.
Fuelling & injector care
Fuelling on the F 800S comes from Electronic intake injection. Cold starts and throttle response stay consistent across altitude and temperature, the main practical edge over a carbureted equivalent.
Brake disc and pad wear
2 x 320mm discs, 4 piston calipers up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.
Suspension condition on used examples
Suspension duties are handled by 43mm Telescopic forks up front and Die-cast aluminium single sided swinging arm with rear wheal axle and eccentric adjustment, central spring stud , spring pre-loaded hydraulically adjustable to continuously variable levels by means of handwheel, rebound damping adjustable at the rear. Weeping fork seals aren't a dealbreaker on a used bike, but they're a fair basis for negotiating price.
Final drive maintenance
Belt final drive keeps day-to-day maintenance minimal on the F 800S - just periodic tension and wear checks rather than the regular cleaning a chain demands.
Frame & chassis check
The Bridge-type aluminium frame chassis holds up well with normal use; on a used bike it's still worth checking the head-stock and swingarm pivot area for impact damage or corrosion.
F 800S - Buying & Maintenance Guide
What to check before buying
A pre-purchase check on the 2008 BMW F 800S with its 798 cc sport should cover the same ground every time: service history, drivetrain condition, and any oil seepage around the casings. This model runs belt final drive, so check belt tension and tooth wear - a cracked or glazed belt is a clear sign of neglect. Now 18 years old, this sport is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept F 800S settles to a smooth idle within seconds.
Oil and filter changes
Oil changes are the cheapest insurance you can buy for the F 800S's 798 cc liquid-cooled parallel twin, dohc, 4 valves per cylinder - keep to the manufacturer's interval rather than stretching it. With a 12.0:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.
Fuel system care
Injector systems like the F 800S's hold up well with basic care - decent fuel, an occasional cleaner additive, and draining old fuel before any layup longer than three months.
