2005 BMW K 1200GT Overview
BMW K 1200GT is a touring motorcycle, displacing 1157 cc. Power comes from an In-line four engine running DOHC valve actuation, a compression ratio of 13.0:1. On the performance side, it delivers 112 kW @ 9500rpm of peak power and 130 Nm @ 7750 rpm of torque. Top speed is factory-quoted at 249.3 km/h. On the road, the 2005 K 1200GT tips the scales at 300 kg, carries a 24 L fuel tank, offers a seat height of 820 mm - 840 mm and spans a 1,550 mm wheelbase. That's roughly 24.1 kg lighter than the average touring motorcycle in our database. The full 2005 BMW K 1200GT spec sheet below covers every technical detail, from suspension travel to tyre sizes.
2005 K 1200GT - Pros & Cons
Strengths
-
⚡
Strong power output: With 112 kW @ 9500rpm and 130 Nm @ 7750 rpm of torque on tap, the K 1200GT 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.
-
⛽
Large fuel range: A 24 L tank means fewer stops on longer rides - a genuine plus for touring or a lengthy daily commute.
-
⚙️
Low-maintenance final drive: Running Shaft final drive cuts out the regular chain cleaning and tensioning that most bikes need.
Considerations
-
📏
Tall seat height: At 820 mm - 840 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
K 1200GT'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 BMSK fuel Injection on the K 1200GT 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 K 1200GT 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 disc, 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 K 1200GT's suspension runs BMW Duolever at the front. The rear uses Single coast aluminium BMW Paralever. Fork-seal condition and rear linkage play are the two things worth checking before buying used.
Final drive maintenance
The K 1200GT uses shaft final drive: essentially maintenance-free day to day, with periodic gear-oil changes the only real service item.
Frame & chassis check
Built around a Composite aluminium frame with IHU/extrusion-pressed profiles and die sections, the K 1200GT's chassis is straightforward to inspect: look for corrosion, cracks or repair welds around stress points like the head-stock and swingarm mounts.
Handling the weight at a standstill
300 kg puts the K 1200GT toward the heavier end of its class. It's most noticeable at walking pace; once underway the mass settles into the handling rather than fighting it.
K 1200GT - Buying & Maintenance Guide
What to check before buying
Before handing over money for a used 2005 BMW K 1200GT, cover the fundamentals: service book and oil change history, chain and sprocket wear, and any sign of oil weeping around the casings. Cold-starting it yourself tells you a lot - a healthy K 1200GT should catch quickly and settle into a smooth idle.
Oil and filter changes
Nothing protects a K 1200GT's engine like disciplined oil changes - stay on the manufacturer's schedule (roughly every 6,000 km or annually). Match the viscosity grade to what the owner's manual specifies, not what's cheapest.
Fuel system care
Fuel injection on the K 1200GT 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 K 1200GT 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.
