What to Check Before Starting a 2018 BMW S1000XR That’s Been Sitting

Returning a 2018 BMW S1000XR to service after storage is a straightforward process when approached methodically. The S1000XR is a fuel-injected, electric-start, liquid-cooled motorcycle, and understanding that configuration determines which checks are relevant—battery and cooling system guidance applies only where those systems are present. Work through the checklist below before attempting to start, and scale each step based on how long the bike has been sitting and what the storage conditions were.
First Things First: Inspecting the S1000XR After Time in Storage
A thorough visual inspection of the S1000XR before attempting to start sets the foundation for a safe return to service. Begin at the tires: check both for sidewall cracks, which appear as a network of small surface lines or as deeper splits in the rubber and indicate that the tire compound has aged past safe use. Look at the contact patch for flat-spotting, particularly if the bike sat in the same position for an extended period.
Beneath the S1000XR, look for any staining or residue on the floor that indicates a fluid leak during storage. The area under the engine is the first to check for oil; the area under the front forks for hydraulic fluid seepage from fork seals; and the area near the calipers for brake fluid that has wept from a degraded seal.
Liquid Cooling System Checks Every S1000XR Owner Should Do After Storage
Check the coolant level in the S1000XR’s expansion tank before attempting the first start after storage. The reservoir has MIN and MAX markings visible through the translucent plastic; coolant that has dropped below the MIN line needs to be topped up before the engine is started. Use the coolant type appropriate for aluminum cooling systems—pre-mixed coolant rather than straight concentrate that needs to be diluted—to avoid incorrect mixture strength.
Coolant hoses on the S1000XR age from the inside and the outside simultaneously: internally from the corrosive effects of depleted or incorrect coolant, and externally from heat cycling and exposure. A hose inspection before the first start involves more than a visual look—it requires squeezing each hose to assess its pliability.
Charging and Terminal Checks Before Starting the S1000XR
Connecting a smart battery charger to the S1000XR’s battery before attempting the first start is the single step that most reliably improves the outcome of a storage restart. Batteries self-discharge over time and can lose enough capacity during a season-long storage to prevent reliable starting, even if they were fully healthy before being stored.
Terminal inspection on the S1000XR’s battery should be part of the pre-start process regardless of how long the bike has been sitting. Moisture, temperature cycling, and outgassing from the battery during storage cause corrosion on terminal posts and clamp contacts that can grow significant enough to interfere with electrical conductivity. Remove both cables—negative first—and inspect the posts and clamp contacts for any white or blue-green deposit.
Fuel System Readiness on the S1000XR After Storage
Before starting the S1000XR after storage, take a moment to assess the fuel in the tank. Open the fuel cap and look at the fuel’s color—fresh gasoline is clear to pale yellow; fuel that has degraded from sitting is darker, often amber or brownish, with a sour or varnish-like smell. Fuel in this condition has less energy density than fresh gasoline and may have moisture contamination from ethanol separation.
The fuel injection system on the S1000XR goes through a self-test sequence when the ignition is switched to the on position. During this sequence, the fuel pump runs briefly to pressurize the fuel rail. Listening for this priming cycle—a brief whir from the fuel tank area lasting about two seconds—confirms the pump is running and the fuel system is pressurizing.
Engine Oil and Drive Chain: Essential Pre-Start Lubrication Checks
Check the engine oil level and condition on the S1000XR using the dipstick or sight glass before attempting to start. The oil level should be between the minimum and maximum marks; top up with the correct oil specification if needed. Inspect the oil’s color and clarity: clean oil is amber to light brown and translucent; contaminated oil is dark black, gritty-feeling, or has a milky appearance.
Drive chain lubrication on the S1000XR is a pre-ride step that often gets skipped during a quick return-to-service after storage, and a dry, rusted chain on the first ride accelerates wear on both the chain and sprockets significantly. A chain that was not lubricated before storage or that shows surface rust needs to be cleaned and lubricated before the bike moves.
Brake Fluid Condition and Control Checks Before Riding the S1000XR
Brake fluid absorbs moisture from the atmosphere at a rate that increases with temperature cycling—exactly the conditions a stored motorcycle experiences. Check the brake fluid level in the front master cylinder reservoir (typically visible through a sight glass or under a cover at the handlebar) and the rear master cylinder.
The throttle, clutch, and any manually operated cable controls on the S1000XR need to move freely through their full range before the bike is ridden. Work the throttle grip through full open and full closed several times; it should move smoothly without sticking at any point in its range and should return to fully closed promptly when released without being held. A throttle that sticks open even partially is a safety-critical defect that must be resolved before riding.
What to Expect When the S1000XR Starts for the First Time After Sitting
When the pre-start checklist is complete and the S1000XR is ready for its first start, be prepared for a slightly different startup experience than normal.
The first ride on the S1000XR after storage is a test ride, not a normal ride. Keep the initial distance short—a few miles in a familiar area where returning to a starting point if something seems wrong is easy—and stay alert to how everything feels. Braking should feel firm and progressive with no pulsation; throttle should respond cleanly and the engine should pull smoothly through its range; the chassis should track straight and corners should feel normal.
