The Royal Enfield Thunderbird 350 is a cruiser motorcycle from Royal Enfield. It has been discontinued (production ended around 2020). Mechiee still services it at your doorstep. Cruisers are built for relaxed riding, typically with a low seat, a laid-back posture and an engine that pulls from low revs. With a 346 cc engine it sits in the 250–450 cc class.
Power comes from a 346 cc single-cylinder air-cooled engine that makes 18.0 bhp at 5,501 rpm and 27.46 of torque. Its stroke is longer than its bore (70 mm x 90 mm), a long-stroke layout that generally favours low-down pulling power. Divide power by kerb weight and it has about 104 PS per tonne; by that measure, there is enough go for confident city riding and relaxed highway cruising. It has both electric and kick start.
It has a 5-speed manual gearbox, and a chain carries drive to the rear wheel. It uses a wet multi-plate clutch.
It is built around a tubular welded frame. Suspension is by telescopic forks at the front and twin gas charged shock absorbers with 5-step adjustable preload at the rear. It has dual-channel ABS. ABS on both wheels keeps either tyre from locking under hard braking. It rides on 19-inch front and 18-inch rear spoke wheels — 90/90-19 at the front and 120/80-18 at the rear.
The seat is 740 mm off the ground, which is low and makes it easy to put your feet down. It weighs 175 kg ready to ride, which is on the heavy side, so moving it by hand takes some effort. Ground clearance is 140 mm — adequate, though tall speed breakers need care. It is 2,120 mm long, with 1,350 mm between the axles. Its 14.45 L fuel tank and claimed mileage of 34 kmpl work out to roughly 491 km per tankful on paper; real-world range is usually lower.
Safety equipment includes low fuel indicator and low oil indicator.

Mechiee doorstep service
₹2,199
Mechiee's fixed doorstep service price for this model.
Follow the schedule in the owner's manual for your exact variant and year. A regular service is the cheapest way to catch small problems before they become expensive ones.
Engine oil is the single most important consumable to keep fresh. Top up between services if the level drops, and change it on schedule.
Check pad or shoe wear, lever and pedal free play, and braking feel at every service.
A clean, correctly tensioned and lubricated chain lasts longer and wastes less power. Check slack regularly, especially after riding in rain or dust.
A clogged air filter or worn spark plug shows up as hard starting, weak throttle response and poorer fuel economy. Both are checked at a regular service and replaced when worn.
This bike runs 90/90-19 / 120/80-18 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.
Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.
