2009 BMW F 800ST Overview
BMW F 800ST is a sport touring motorcycle, displacing 798 cc. Power comes from a Liquid-cooled parallel twin, DOHC, 4 valves per cylinder engine running DOHC valve actuation, a compression ratio of 12.0:1. On the performance side, it delivers 62.5 kW @ 8000 rpm of peak power and 80 Nm @ 5800 rpm of torque. Top speed is factory-quoted at 220 km/h. On the road, the 2009 F 800ST tips the scales at 201 kg, carries a 16-litre fuel tank, offers a seat height of 820 mm and spans a 1,466 mm wheelbase. That's roughly 41.2 kg lighter than the average sport touring motorcycle in our database. The full 2009 BMW F 800ST spec sheet below covers every technical detail, from suspension travel to tyre sizes.

2009 F 800ST - Pros & Cons
Strengths
-
⚡
Strong power output: With 62.5 kW @ 8000 rpm and 80 Nm @ 5800 rpm of torque on tap, the F 800ST is no slouch for its class.
-
🔧
Fuel injection: Fuel injection means consistent cold starts and clean throttle response without the fussiness of a carbureted setup.
-
🛑
Strong front braking: Stopping power up front is strong thanks to the disc setup, with plenty of room to upgrade further with braided lines.
-
⚙️
Low-maintenance final drive: Running a belt final drive cuts out the regular chain cleaning and tensioning that most bikes need.
Considerations
-
📏
Tall seat height: At 820 mm, shorter riders will likely be on tiptoes at a standstill - worth sitting on one before you buy.
Wear Points & Servicing Notes
Cooling system servicing
F 800ST's Liquid cooled setup is low-maintenance provided the coolant interval is kept - old, acidic coolant is the main cause of long-term corrosion in the water passages.
Fuelling & injector care
The Electronic intake injection on the F 800ST needs little beyond good fuel and periodic use of an injector-cleaner additive - no jetting or float-bowl maintenance to worry about.
Valve clearance checks
With DOHC valve gear, the F 800ST needs periodic clearance checks; caught early they're a cheap adjustment, left unchecked they accelerate valve seat wear.
Brake disc and pad wear
Braking up front comes from 2 x 320mm discs, 4 piston calipers - solid stopping power, with disc and pad wear best checked on the same schedule as tyre changes.
Suspension condition on used examples
The F 800ST's suspension runs 43mm Telescopic forks at the front. The rear uses 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. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The F 800ST runs belt final drive: no lubrication or frequent adjustment like a chain, though belt tension and wear are worth a periodic look.
Frame & chassis check
Built around a Bridge-type aluminium frame, the F 800ST's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
F 800ST - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2009 BMW F 800ST with its 798 cc sport touring, cover the fundamentals: service book and oil change history, drivetrain wear, and any sign of oil weeping 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 17 years old, this sport touring is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Cold-starting it yourself tells you a lot - a healthy F 800ST should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects the F 800ST's 798 cc liquid-cooled parallel twin, dohc, 4 valves per cylinder like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). With a 12.0:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Fuel system care
Fuel injection on the F 800ST needs little attention beyond decent fuel and an occasional system-cleaner additive. Anything left standing for three months or more should have its fuel drained and replaced before it varnishes the injectors.
Valve clearance service
Valve clearances are easy to overlook on a used F 800ST since a bike out of spec doesn't always feel obviously wrong - but the wear it causes is real. Ask the seller for documentation before assuming it's been done.
