1290 Super Duke R

• Brembo radial master cylinder plastic piston cracking — recall (NHTSA Recall 18V-033) Recall 18V033000 The plastic (PPS polymer) piston in the front master cylinder could crack or break under heavy load, hard ABS engagement, or after a tip-over, leading to loss of front-brake function. Remedy: dealer replaces the plastic piston with an aluminum piston.
• Fuel tank threaded-insert leak — recall (NHTSA Recall 15V-441) Recall 15V441000 Threaded inserts at the rear of the plastic fuel tank could leak fuel due to a coating-process irregularity in tank manufacture. Risk of fuel ignition if combined with an ignition source. KTM notified affected owners; remedy was inspection and sealing of the inserts, or tank replacement where an existing leak was found.
• Radiator top-rail seam splitting The top-right (sometimes top-left) seam of the radiator splits along the upper rail. Owners attribute the failure to radiator-mount design and stress transfer from the freely-rotating exhaust clamp. Symptom: visible coolant weep from the upper radiator seam, eventual coolant loss and overheating risk.
• Clutch slave cylinder rubber-seal swelling and air ingress The OEM clutch slave cylinder rubber seal swells over time, causing internal corrosion and air ingress in the hydraulic line. Symptoms: milky or dark clutch fluid, hard-to-find neutral, hot-clutch fade, repeated bleeding required. Re-sealing rarely lasts; owners typically replace with billet aftermarket units (Oberon, Rottweiler).
• Hydraulic cam chain tensioner loses pressure The factory cam chain tensioner is hydraulic and runs on engine oil pressure. It can bleed down or fail to hold pressure, which leaves the timing chain slack. The usual symptom is a ticking or rattling noise from the cam chain area, most noticeable at idle or just after a cold start before oil pressure builds.
• Fuel pump failure — low fuel pressure, stalling, no-start "Fuel Pump Failure" warning, bike cuts out, hangs at approximately 5,500 rpm, will not restart. KTM identified the fuel filter and/or pump motor as the cause of low fuel pressure; a replacement kit (seals, gaskets, filters, motor) is supplied by the dealer.
• Rear wheel bearing failure due to swingarm water ingress The Gen 1 single-sided swingarm has no internal drain hole. Water collects inside the swingarm, corroding the rear wheel hub bearings. Symptoms: vague "steering" feel from the rear wheel under on/off throttle. Owners frequently find a half-cup of water when removing the axle adjuster. KTM addressed this on the Gen 2 swingarm by adding a drain hole — a tacit confirmation of the Gen 1 design defect.
• Side-stand sensor failure — no-start or stalling Side-stand sensor fails — often a magnet-related fault contaminated by chain-area debris. Bike will not start or stalls when in gear. The 1290 sensor uses a 50% duty-cycle pulse, so a simple bypass requires a dedicated dongle (Rottweiler, Vanasche).
• Jerky on/off throttle transition at low rpm Snatchy on/off transition at 2,500–3,500 rpm, particularly noticeable in Rain mode. Stock fueling is lean for emissions compliance. Many owners install aftermarket fueling modules (Rottweiler, Power Commander) or apply ECU updates from the dealer; outcomes vary.
• Front fork seals develop weeping / "tide marks" The seals on the WP upside-down fork can start to weep over time. Oily tide marks show up on the fork tubes just below the seals. The leak tends to come on gradually with use rather than being present from new. If left alone, the seeping fork oil leaves a residue that collects road grime and slowly lowers the oil level in the affected leg.
• Front brake light switch error / brake light stuck on Omron switch on the Brembo master cylinder fails. "Front Brake Switch" error appears on the dash; brake light may be stuck on, or a fault code is logged. Wire-routing strain at the master cylinder is the documented cause. Some owners report MTC (traction control) faults as a downstream side effect.

Speed Triple R

• Electrical short from chafing wire (recall) Recall 17V700000 The generator link lead wire may rub against the ABS modulator bracket, damaging insulation and causing an electrical short that can lead to engine stalling. Triumph recall SB552 / NHTSA 17V700000 affected 541 units and required wire replacement and rerouting free of charge.
