1 | T509 (1997–1998)-The 885 cm³-in-injection triple

Internal type code T509 characterizes two years that although "955" did not yet know in the name, but paved the way there. The 885 cm³ Three-cylinder (76 mm × 65 mm) was the first triumph series engine to receive a Full sequential sagem injection, controlled by a 16-bit ECU. Performance: 108 hp, torque: 82 Nm. Weighing ready for driving: 207 kg - for the 90s sensationally little. Core parts that are today with the original remaining or Decide aftermarket quality:

Typical weaknesses: 40-ampere controls behind the battery cooks Stow wing-replacement by MOSFET FH020AA prevents 15 V spikes. Added the Sprag-Clutch (Stay of the starter): it slams at the cold start, is Mostly feather t3800055 tired - equally installed kit with 18 roles. A Deformed cooler (T2106140) lets water temp increase> 105 ° C; a Aluminum replica of Pro-Race Saves 600 g and 6 ° C.

2 | T509 955i (1999–2001)-The first real 955-big bore

The Speed ​​Triple 955i now made 118 PS @ 9 100 RPM and 100 Nm @ 7 000 RPM. Sagem Mc2000-ECU increased injection cycle to 16 kHz, lambdarage came later. Parts, that keep this generation alive:

Maintenance basics: 10W-40 full synthesis every 6,000 km; Valve game 0.10 / 0.20 mm every 12,000 km, Shims 8.9 mm. TPS reset after each Battery change via Tuneticu. Cooling agent (OAT) All 2 J. Cyclists 6205-2RS Replace at the back when heights> 0.4 mm. Ex-up flap was not yet Topic-exhaust is 4-2-1 without servo.

3 | 955i (515NJ / 608) 2002–2004-Radial brakes & SSSA era

The new one settled in the engine Keihin-Ecu with 32-bit architecture, blower for intake temperature sensor and OBD blink code. Peakpower rose to 123 hp, torque remained 100 nm.

Known weaknesses: Soft machine stator overheated Daytime running light + heating handles - MOSFET controller FH020AA With 12-AWG cables Stabilizes 14.2 V. The SSSA needle bearing bolt eats without fat-everyone Saint 10,000 km. Injection valve-o-rings tend to Use ethanol source-Viton set T1241000.

4 | Daytona 955i - engine relatives & parts compatibility

The Daytona T595 (1997) and later Daytona 955i Share cylinder head, crankshaft, injection and often gearbox With the Speed ​​Triple 955. Differences: Sharpered cams, 12.0: 1 compression, 68 mm throttle valve and ex-up valve off 2002. Interesting for Speed-Tuner:

• ✓ Daytona cam T1140505/506 – +6 hp lace, idling remains calm.
• ✓ 68 mm Throttle-Bodies – Plug-and-tune via Tuneticu Map 10172, AFR 13.0.
• ✓ Daytona oil cooler 10 series- 600 g lighter, requires L-shaped lines.

Gearbox parts are interchangeable 1: 1, coupling basket identical. Speedometer lines Vary, but ABS only existed from 1050 generation. A daytona swing fits in Speed ​​Triple until 2001 with distance sleeve +5.2 mm; 515NJ-SSSA leaves Conversely, do not work without milling.

5 | Maintenance rhythm & wear parts

Triumph specifies SAE 10W-40 semi-synthetic; bring Ester oils (Motul 7100 15W-50) 5 ° C less oil temperature. Change everyone 6,000 km, oil filter T1218001 + Crush-Washer T3600035.

In Forums (triplplantalk, rat.net) Springs, free runs, Used SSSA wheels and tuneecu map repositories exchanged. Hilltop dyno (De/UK) offers flash mapping for 68 mm bodies, while TEK details Finished MOSFET cable trees made.

9 | Competition & collector status

The first 955i SSA models (2002 silver) increase by 8 %per year. T509 885 CC remains a cult, couples price to original condition and headlights ("Bug-Eyes").
