Abrupt off-on throttle response on overrun
engine very common
The ECU cuts fuel 100 % on overrun for emissions compliance, then reapplies it abruptly when the rider re-opens the throttle. Most noticeable in city / low-gear riding and on corner exits. Owner-side workarounds include TPS reset, Booster Plug, O2 eliminators, and Woolich ECU reflash.

Helmet-level turbulence above high speeds with the standard screen
bodywork occasional
The windscreen's airflow sends turbulence to helmet level at sustained highway speeds, and taller riders feel it most. The Travel Edition comes from the factory with the taller touring screen and an adjustable windshield. This reduces the buffeting but does not fully remove it, so some riders still fit an aftermarket touring screen with a different profile.

Buzzy mid-RPM vibration band at 6th-gear cruise speeds
engine common
Vibration intensifies in a roughly 5,000–6,500 rpm band, which coincides with typical 6th-gear cruise speeds in the GT's short-geared final drive. Mirror blur is widely reported; comfort impact varies by rider. Owner-side workarounds: heavier bar-end weights, BB-fill, aftermarket pegs, or final-drive sprocket change (+1 front or −1 rear) to drop cruise rpm. Suzuki characterises the behaviour as "normal" — no formal action.

mySPIN connectivity dropouts and pairing failures
electrics common
The TFT's Bosch mySPIN smartphone-mirroring system experiences dropouts after ignition off-on cycles, failure to re-pair on iPhone, phone overheating during use, and app crashes during navigation. Bosch / Suzuki have addressed individual issues via app updates rather than firmware; multiple page-long forum threads document the pattern across iOS and Android. Note: the GT does **not** support Apple CarPlay or Android Auto — mySPIN is the only mirroring system.

Pannier lock failures and inner-bag fitment / wear issues
bodywork occasional
Multi-owner forum reports of locks failing or falling out of the OEM pannier housings, OEM inner bags fitting poorly (≈ 0.3" gap each side), and zipper / fabric wear within the first 1,000–2,000 miles. Pannier plastics scratch where dust collects between bag and case. Travel Edition–specific because the cases are factory-fitted on this trim.
-
Cam-chain tensioner rattle on hot start
engine common
Deep tapping / rattling for ≈ 3–5 seconds on hot starts, originating at the cam-chain-tensioner side of the cylinder head; subsides once oil pressure builds. Suzuki dealers have characterised the noise as "normal" while quietly replacing tensioners under warranty in some markets. The tensioner design was reportedly revised mid-cycle. No engine failures attributable to the rattle have been reported.
-
Cruise control fails to set or drops out with dash icon blinking 2–3 times
electrics occasional
Cruise control refuses to set, or drops out after activation, with the dash icon blinking 2 or 3 times. Owner-side workarounds: only set cruise within the first few minutes of a ride; cycle the ignition off-on to reset. Some dealers have replaced the brake-light switch or adjusted clearance with mixed results. No formal TSB / recall identified as of 2026-05-06.

Thin paint in places; fasteners and connectors corrode in winter without diligent cleaning
bodywork occasional
Thin paint and fasteners/connectors that corrode quickly when the bike sees winter use without diligent washing. Tank-side paint wears where rider knees, belt, or boots rub — reflected in aftermarket tank-pad demand (Eazi-Grip, Motografix). Cosmetic, not structural.
