1982 Suzuki GSX 1100S Katana Overview

For 1982, Suzuki offers the GSX 1100S Katana as a classic motorcycle with 1074 cc on tap. The 1982 Suzuki GSX 1100S Katana is built around an In-line four, four-stroke engine running DOHC valve actuation, a compression ratio of 9.5:1. Internally, bore and stroke are 72 x 66 mm. Out on the road, the GSX 1100S Katana delivers. Flat out, it's quoted at 228 km/h. In everyday use, the 1982 GSX 1100S Katana tips the scales at 272 kg and carries a 21-litre fuel tank. That's roughly 76 kg heavier than the average classic motorcycle in our database. Every technical detail, from suspension travel to tyre sizes, is covered in the full 1982 Suzuki GSX 1100S Katana spec sheet below.

1982 Suzuki GSX 1100S Katana compared with other bikes in the Classic category

Measured against other bikes in the Classic category in our database (up to 909 models, one entry per model), the 1982 Suzuki GSX 1100S Katana comes out as follows.

Versus the 1981 model

The figures we track are unchanged from the 1981 model: wet weight, displacement and top speed all match.

1982 GSX 1100S Katana - Pros & Cons

Strengths

Strong front braking: The dual disc front brake bites hard and stays consistent - a solid foundation whether it's stock or upgraded with braided lines.
Large fuel range: With a 21-litre tank, this isn't a bike you'll be stopping for fuel every hour - a real asset on longer trips.

Considerations

Chain final drive upkeep: A chain drivetrain is the most common setup in its class, but it's also the one that demands the most regular hands-on maintenance.

Wear Points & Servicing Notes

Valve clearance checks

Valve clearances on DOHC-equipped engines like the GSX 1100S Katana's drift slowly with mileage rather than failing suddenly - sticking to the service interval keeps it a non-issue.

Brake disc and pad wear

Dual disc up front provides the primary stopping power; inspect disc thickness and pad wear at each tyre change to catch scoring before it becomes a rotor replacement.

Final drive maintenance

Chain final drive on the GSX 1100S Katana means routine lubing and tension checks are part of ownership - skip them and sprocket wear accelerates noticeably.

Handling the weight at a standstill

The GSX 1100S Katana's 272 kg kerb weight is worth factoring into how you handle it at a standstill - parking-lot manoeuvres need a bit more deliberate technique than on a lighter machine.

GSX 1100S Katana - Buying & Maintenance Guide

What to check before buying

A pre-purchase check on the 1982 Suzuki GSX 1100S Katana with its 1074 cc classic should cover the same ground every time: service history, drivetrain condition, and any oil seepage around the casings. This model runs chain final drive, so check chain slack and sprocket tooth profile specifically - a worn sprocket is a cheaper fix now than after it's chewed up the next chain. Now 44 years old, this classic is as likely to show age-related wear (perished rubber, seized fasteners, degraded seals) as mileage-related wear. Start it from cold if you can - a well-kept GSX 1100S Katana settles to a smooth idle within seconds.

Oil and filter changes

Oil changes are the cheapest insurance you can buy for the GSX 1100S Katana's 1074 cc in-line four, four-stroke - keep to the manufacturer's interval rather than stretching it. With a 9.5:1 compression ratio, running the octane grade specified in the manual matters more than on a lower-compression engine. Use the viscosity grade the manual specifies, not whatever's on sale.

Valve clearance service

There's no reliable seat-of-the-pants way to tell if a GSX 1100S Katana's valve clearances are in spec - a light top-end tick is the only real warning sign, and by then some wear has already happened. Service records are the only proof.
