1991 Suzuki GSX600 0.6L Petrol · J484 SUK

As a 599cc petrol motorcycle, running costs are generally moderate. Fuel economy will depend heavily on riding style, but mid-sized commuters of this era are typically efficient. Tax and insurance groups for a 1991 machine are often lower than modern equivalents, though insurance can be influenced by the rider's age and experience.

Maintenance costs for a vintage Suzuki will involve more frequent checks of rubber components, seals, and fluids due to the vehicle's age. Expect to budget for periodic tyre replacements and chain maintenance. An estimated annual running cost for this bike, including fuel and basic servicing, would fall in the mid-range for a classic motorcycle.

Focus heavily on the steering geometry; the repetitive 'stiff or notchy' steering head bearing advisory suggests the bearings are nearing the end of their service life. Move the handlebars from lock to lock while stationary to feel for any catching or resistance.

Secondly, scrutinise the rear braking components. Since the MOT history notes a fluctuation in brake effort, check the rear brake disc for uneven wear or scoring, and inspect the brake caliper for leaks. Ensure the brake fluid is clear and not contaminated, as the repeated advisory suggests a persistent issue with the hydraulic feel or mechanical application.
