The 2013-2016 generation has a well-documented pattern of regulator/rectifier failures: batteries draining while riding and no-starts after highway runs.
Watch for: Battery draining while riding, flickering headlight, no-start right after a long highway run
Do this: Verify charging voltage (13.8-14.4V at 5,000 rpm) at services and fit an upgraded reg/rec if the original fails.
Typical cost: ₹2,500–₹6,000

Hard-ridden Dukes commonly need a full chain-sprocket kit between 18,000-25,000 km; adjusters near the end of travel are the giveaway.
Watch for: Adjuster marks near the end, hooked sprocket teeth, tight spots and lash together
Do this: Lube every 500 km, avoid pressure-washing the chain, and budget for a kit around the 20,000 km checkpoint.
Typical cost: ₹4,500–₹9,000

Strong brakes plus aggressive use equals pads done by 6,000-12,000 km in many city-riding reports.
Watch for: Growing lever travel, heavy black dust on the front wheel, metallic scrape when worn out
Do this: Inspect pads every 3,000 km, fit quality pads, and bed them properly after replacement.
Typical cost: ₹1,200–₹3,200

2017-2019 Dukes with the first TFT dash have known condensation reports after rain; many were replaced under warranty.

Do this: Park covered in monsoon and pursue warranty replacement early; out-of-warranty displays are expensive.
Typical cost: ₹0–₹8,000

A high-frequency buzz through the tank and seat around 7,000-8,500 rpm is widely reported as engine character on long highway pulls.
Watch for: Numb inner thighs on long highway stints, buzzy pegs near the band
Do this: Treat mild buzz as character, but get engine mounts checked if it appears suddenly or worsens.
Typical cost: ₹0–₹500

Track-day and drag-happy owners report clutch slip past 15,000 km: revs rise without matching speed in higher gears.
Watch for: RPM flare without acceleration in 4th-6th, burnt smell after hard runs
Do this: Use JASO MA2 oil only, keep free play in spec, and inspect plates at 20,000 km if you ride hard.
Typical cost: ₹3,000–₹8,000
