## Fair-value range (UK asking prices)

- **Typical:** £300
- **Range:** £250 to £350
- **Original price:** about £525 when new (median of 9 used-market listings quoting one), so the current used value holds roughly 57% of it
- **If you are pricing one to sell:** £350 to £400 depending on model year. Do not quote the typical figure above as an asking price for a specific bike: it sits outside every model year measured below. Use the model-year table.

## Measured asking price by model year (19 real UK listings that state a model year)

Median last-advertised asking price per model year. Asking prices, not confirmed sale prices.

These are a different set of listings from the headline figure above: 29 of the 100 listings state a model year, and their median is £350. Compare a model year below against £350 rather than against the all-listings median.

| Model year | Median asking price | 95% confidence range | Listings |
|---|---|---|---|
| 2026 | £400 | £300 to £400 | 9 |
| 2025 | £350 | £300 to £400 | 10 |

The range is a 95% confidence interval on that year's median, not the spread of listing prices. Where two years' ranges overlap, the difference between those years is not established by this data.
