Engine architecture
Air-cooled four (then nothing)
Both XJR1200 (1995-1998) and XJR1300 (1998-2017) used the same fundamental air-cooled DOHC inline-four — derived from the 1980s FJ1200 motor. 22 years of production with no liquid-cooling switch (unlike the Suzuki Bandit which transitioned in 2007). After 2017 Yamaha stopped making air-cooled fours entirely. The XSR900 is a 3-cylinder, the MT-09 the same, the MT-10 a CP4 four — but liquid-cooled.
XJR1200 → XJR1300
+63cc displacement, 1998
The 1998 transition from XJR1200 to XJR1300 was straightforward: 1188cc bumped to 1251cc, power up from 97bhp to 105bhp, torque up from 99Nm to 108Nm. Same air-cooling, same chassis, same retro twin-shock styling. Fuel injection didn't arrive until 2007, almost a decade after most rivals had switched.
Why it ended
Euro 4 emissions, 2017
Euro 4 came in January 2017 and the XJR's air-cooled four couldn't be cost-effectively updated for the much tighter NOx/HC limits — the same fate that killed Honda's CB1100 in 2020 and Suzuki's Bandit in 2016. Yamaha capped XJR1300 power at ~98bhp from 2015 to ease the homologation burden, but the maths didn't work. The bike was killed after the 2017 model year.
Yamaha's air-cooled four-shaped hole
9 years and counting
Yamaha has not built an air-cooled inline-four since 2017. The XSR900 (£10,475, 117bhp parallel triple) is the modern retro — but a three-cylinder bike with a different character. The retro inline-four formula is now Triumph (parallel twin Bonneville T120) and Kawasaki (Z900RS, but liquid-cooled). The Japanese big-four retro inline-four is essentially extinct in 2026: XJR1300 gone 2017, CB1100 gone 2020, Suzuki Bandit gone 2016.
Real cost trajectory
Held flat for 20 years
£7,500 XJR1200 in 1996 (£15,000 today) → £7,500 XJR1300 in 2006 (£12,600 today) → £10,000 XJR1300 Racer in 2016 (£13,000 today). Yamaha priced the XJR consistently in real terms — never cheap, never premium, always positioned as a mid-tier muscle-retro. Used market in 2026: XJR1200 £2.5-4k, XJR1300 £3-5k, XJR1300 Racer £5-7k for clean low-mile.
Rider aids count (1996 → 2026)
0 → 0
XJR1200 had nothing. XJR1300 added ABS in 2014 and fuel injection in 2007 — both very late by industry standard. 2026 XJR equivalent: nothing — because Yamaha doesn't make one. The XSR900 has cornering ABS, traction, ride modes, IMU, full electronics — different bike entirely.
Cheapest way in
£2.5k
A clean XJR1200 from the late 90s. Air-cooled four, twin shocks, classic UJM look, no electronics. The cheapest 1200cc retro four on the UK used market — and a serious cult bike now. FJ1200 motor is bombproof; pay attention to reg/rec and stator on high-mile bikes.
