British supersport that beat Japan
2006 reset
When Triumph launched the Daytona 675 in 2006 it was widely tested as faster than Honda CBR600RR and Yamaha R6 in mid-corner — the three-cylinder gave it V-twin-style mid-range punch with four-cylinder top-end. MCN 2006 supersport group test put the 675 ahead of the Japanese big four. Triumph's first credible WSBK-class supersport bike. Defined Triumph's modern brand.
675 → 675R (2011)
Premium track variant
2011 Daytona 675R (R = Race) added Öhlins NIX30 inverted forks, Öhlins TTX36 rear shock, Brembo monobloc front brakes, red rear shock spring. $1,500 premium over standard 675. Most desirable on used market — the premium suspension still has value 9 years after end of production.
Why it ended 2017
Euro 4 + supersport collapse
Two factors killed it. Euro 4 in 2017 required engine redesign that wasn't cost-effective. AND supersport segment sales collapsed 2010-2017 as buyers moved to ADV bikes and naked nakeds. Yamaha R6 went track-only in 2020; Honda CBR600RR became grey-import only. The 'middle-weight supersport' category is essentially extinct in Europe.
vs Daytona 660 (parallel-twin)
Different bike entirely
2024+ Daytona 660: 660cc parallel-twin from Trident 660, 95bhp, 69Nm, 200kg wet. Friendlier, less track-focused, A2-friendly with restrictor, $8,895. The 660 is a 'sport tourer in supersport bodywork' — the 675 was a proper track-bike with road kit. Different riders entirely.
Real cost trajectory
+17% real (vs 660)
$7,499 Daytona 675 in 2006 ($12,600 today) → $8,895 Daytona 660 in 2026. Modern bike is cheaper in real terms. Used market in 2026: Daytona 675 standard $3.5-6k, 675R $6-9k for clean low-mile. The 675R is the buy for trackday riders — Öhlins suspension is the differentiator.
Rider aids count (2006 → 2026)
1 → 6
Daytona 675 (2006) had FI as the only rider aid. By 2013 it had ABS, traction control, ride modes. 2026 Daytona 660 has cornering ABS, traction control, ride modes, optional quickshifter. Modern parallel-twin supersport has more rider aids than the 2013 675R but less raw character.
Cheapest way in
$3.5k
A clean Daytona 675 from 2006-2010. 124-128bhp triple, FI, slipper clutch, that classic Triumph three-cylinder character. Pay attention to fuel pump priming, reg/rec, fork seals. The cheapest path to a British supersport with real WSBK pedigree (Daytona 675 won World Supersport in 2014). Properly undervalued in 2026.
