How the scoring works

Every bike gets a score out of 100, computed by the same deterministic formula from published spec data. No editorial adjustment, no sponsored thumb on the scale. This page is the entire system; if you can read a spec sheet, you can reproduce our numbers.

Normalization: bikes only compete inside their class

Raw numbers are never scored directly. Each input is min-max normalized against the other bikes in the same class (we call it a segment): the best value in the class scores highest, the worst lowest, everything else lands proportionally between. A commuter single is measured against commuter singles, not superbikes. Where lower is better, like weight or price, the scale flips.

Small classes get smoothing. Raw min-max in a two-bike class is winner-take-all: every metric would score 0 or 1, which overstates real gaps. So every normalization blends in two neutral pseudo-entries at 0.5. A two-bike class scores between 0.25 and 0.75 per input, a large class approaches pure min-max, and the ranking inside a class never changes. If a class has no second bike at all, the input scores a neutral 0.5.

Technology (10 points)

Technology is a weighted checklist rather than a class-relative metric, so a bike is rewarded for what it ships with, full stop.

The tier tables

Hardware that resists a single number, like suspension or brakes, scores through fixed tiers. These tables are imported from the same code the scoring engine runs, so what you read here is what the engine executes.

Warranty scores linearly up to full marks at 4 years. Each well-documented reliability issue costs 25% of the known-issues component.

Worked example: KTM 390 SMC R

Applying all of the above to the KTM 390 SMC R inside its class produces 68.3 points. The component detail below is the engine's actual output, not a copy.

What the score does not capture

Feel. A spec sheet cannot measure how an engine builds revs or how a chassis talks to you at lean. The points tell you which bike wins on paper and by how much; the verdict text on each comparison adds the judgement calls, clearly separated from the math. When specs are updated or corrected, scores recompute automatically.
