Use our detailed year-by-year breakdown and failure analysis below to understand how your specific R27 is likely to perform.
Motorcycle steering and suspension — 2.0% of failures
Motorcycle steering and suspension issues account for 2.0% of MOT failures on the BMW R27. Suspension failures typically involve worn bushes, leaking shock absorbers, broken coil springs, and damaged suspension arms. These affect ride quality, tyre wear, and road holding. Typical repair costs: £200–500. Pre-MOT check: Look for uneven tyre wear, listen for clunking over bumps, and check if the car pulls to one side. A bouncy ride suggests worn shock absorbers. Visually inspect coil springs for cracks.
Motorcycle lighting and signalling — 2.0% of failures
Motorcycle lighting and signalling issues account for 2.0% of MOT failures on the BMW R27. Motorcycle lighting and signalling issues are a common cause of MOT failure. Regular inspection and maintenance of these components helps ensure your vehicle passes its MOT. Typical repair costs: £100–400. Pre-MOT check: Have this system checked during regular servicing. Look for warning signs like unusual noises, vibrations, or dashboard warning lights.
Motorcycle body and structure — 1.0% of failures
Motorcycle body and structure issues account for 1.0% of MOT failures on the BMW R27. Body and structure failures include excessive corrosion, sharp edges, loose panels, and damage to the vehicle frame. Rust is the primary concern, especially on older vehicles or those exposed to road salt. Typical repair costs: £100–500+. Pre-MOT check: Inspect sills, wheel arches, door bottoms, and the chassis for rust. Surface rust is acceptable but structural corrosion or holes will fail. Check that all doors, bonnet, and boot close securely.
