Suzuki Bandit 600

I put 22,000 kilometres on a '97 GSF600 and it never once left me stranded, which says everything about that air-cooled motor — it's indestructible, characterful, and pulls hard from 5,000 rpm all the way to the redline with a raspy inline-four howl that liquid-cooled bikes simply can't replicate. The naked chassis is flickable and honest, steering with just enough weight to feel planted at motorway speeds without punishing you in town, though the stock seat turns to concrete after about 90 minutes and the suspension is clearly budget-spec from the factory — rebound damping is approximate at best. That front brake setup is the one area where the Bandit's age really shows; the single-disc original equipment needs a firm, deliberate pull and upgraded pads are basically mandatory if you're riding it hard. Still, for the money these things trade at now, nothing else offers this combination of bulletproof reliability, accessible performance, and the kind of riding engagement that actually makes you a better throttle-and-brake technician.

I put nearly 18,000 km on a 2002 GSF600S and the thing simply refused to disappoint me. The inline-four pulls cleanly from about 4,000 rpm and absolutely wails past 8,000 — it's not exotic, but it's genuinely rev-happy in a way that keeps you grinning on a twisty B-road. The Gen 2's revised front brake setup is a real improvement over the earlier bikes; still not razor-sharp by sportsbike standards, but confidence-inspiring enough that you stop thinking about it. My main gripe is the carburetion — cold starts require patience and the flat spot just off idle in cool weather never fully went away no matter how many times the carbs were synced.
