Zontes GK350

Overview

Performance And Engine

The 348cc single-cylinder, DOHC, liquid-cooled engine meets BS6 Phase 2 standards and uses electronic fuel injection with a 12.3:1 compression ratio and an 84.5 x 62mm bore and stroke. It produces 39.33PS at 9500 rpm and 32.8 Nm at 7500 rpm, giving strong mid-range performance for overtaking. Indian riders report a sharp throttle response, though the airbox can be noisy and vibrations are noticeable between 4000 and 6000 rpm, which rubber mounts help reduce. The engine uses wet-sump lubrication and an electric start for reliability, and a chain drive for efficient power delivery.

On the highway, the bike accelerates quickly after 80 kmph and can reach 100 kmph in less than 10 seconds, helped by its light 188kg kerb weight. Eco mode is best for smooth city riding under 60 kmph, while Sport mode allows for more spirited rides. Testers appreciate the stability from the 1380mm wheelbase but mention that the engine can get hot in traffic and there is some lag at low speeds below 3000 rpm. The dual-channel ABS, with 320mm front and 265mm rear discs, gives riders more confidence when braking on uneven roads.

The 6-speed manual gearbox follows a 1-down-5-up pattern with a wet multi-plate slipper clutch to curb rear-wheel hop during downshifts. Ratios emphasise cruising, with fifth gear ideal for 80-100 kmph efficiency. User feedback highlights notchy shifts at cold or hot temperatures, which are improved with deliberate lever inputs; a lack of a quickshifter limits track appeal. The chain final drive requires periodic tensioning, standard for this class in India.

According to the manufacturer and tests, the bike can reach a top speed of 140-145 kmph and holds speeds above 110 kmph with little vibration. The 17-litre fuel tank allows for trips over 400 km, especially if you ride in an aerodynamic position. In real-world use, a solo rider with 40 psi tyre pressure gets the best performance, but with a passenger, the top speed drops to about 135 kmph.

Mileage And Fuel Efficiency

The bike is certified at 31.25 kmpl under IDC standards, thanks to its efficient fuel injection and liquid cooling. This gives it a range of about 530 km, which is strong for its class. These figures are based on lab tests with moderate loads, so real-world mileage may change depending on traffic.

Indian users average 25-28 kmpl overall, with city (stop-go) at 24-26 kmpl and highways (steady 80 kmph) at 28-30 kmpl—users log 26.7 kmpl in mixed conditions. Factors include aggressive riding dropping to 22 kmpl, while conservative styles hitting 30+ kmpl; expect a practical 450 km range. Maintenance, such as cleaning air filters, boosts figures by 1-2 kmpl.

Build Quality

The steel trellis frame works well with the pressed steel swingarm, giving the bike strength without adding extra weight. The welds are neat, and the powder-coated finish helps prevent rust in humid or rainy weather. The 17-inch alloy wheels have reinforced spokes to handle potholes. The paint on the fuel tank and side panels resists chips from highway debris, and the chrome parts, like the exhaust tips, stay shiny after washing. Long-term tests in India show no corrosion even after 5000 km.

Premium details include knurled footpegs for better grip in the rain and sealed suspension linkages that reduce maintenance needs. The fuel filler is designed to keep water out, and the 17-litre tank has internal baffles to prevent fuel from sloshing on rough roads. There are some minor issues, like the TFT display lagging in extreme heat, but overall, the build quality matches that of well-known brands. The reinforced subframe and bash plate add to the bike’s durability on rough Indian roads.

Handling

The mid-mounted engine and 188kg kerb weight give the bike a low center of gravity, making it easy to change direction. The 24.5° rake and 94mm trail provide neutral steering, which is great for winding roads or city U-turns without wobble. The front 43mm USD forks and adjustable rear monoshock, both with 120mm travel, handle bumps well and keep the bike stable even when leaning at 120 kmph. The MRF or CST tyres warm up quickly, giving riders confidence when cornering on loose surfaces.

The twin 320mm petal discs at the front with four-piston radial calipers, along with the 265mm rear disc, provide strong and smooth braking. The bike can stop from 100 kmph to zero in less than 40 meters on hot roads. Testers have noticed a little flex during hard cornering but overall praise the chassis feedback, making it suitable for both new and experienced riders.

Comfort

The 795mm seat height with slim tank allows flat-footing for shorter riders (160cm+), complemented by an 830mm width for knee grip: sculpted foam reduces fatigue on 300km days, and adjustable brake/clutch levers (4 positions) fit glove sizes. Vibration damping via rubber engine mounts keeps mirrors clear above 60kmph, though mirror stalks transmit buzz in city crawl; wind protection from a small fairing suffices up to 110kmph without buffeting.

The pillion seat is more comfortable thanks to fold-up footpegs, but there is no backrest, so riding with a passenger is best for short trips. Ducted cooling vents help manage heat in the summer, keeping the rider’s thighs cooler. The suspension is tuned for comfort rather than sportiness, handling speed bumps well, but if you carry heavy loads, you may need to stiffen the rear preload for better stability.

Styling

The Zontes GK 350 has a bold neo-retro roadster look, featuring a muscular, boxy fuel tank with ‘GK’ graphics. Its large, round LED headlamp contains five projectors for a sharp appearance, and rugged disc covers and indicator protectors add to its tough, adventure-ready style. Bar-end round mirrors give it a classic feel, while the slim LED taillight and upswept dual-barrel exhaust create a striking rear view that stands out in traffic.

The bike’s aluminium alloy panels, steel pipe frame, and 17-inch spoked tubeless wheels combine classic cafe racer style with modern toughness. It measures 2070mm in length, 845mm in width, and 1120mm in height, giving it a solid presence. Exposed engine cooling fins and knurled details on the levers and footpegs add to its premium and practical feel, making it well-suited for Indian roads. The black version of the Zontes GK 350 highlights its eye-catching neo-retro design, from the round headlight to the gold wheel accents.

Colour Options And Variants

Zontes offers the 350R in three eye-catching colours in India

1. Black Blue
2. Orange Silver
3. Gold Black

These matte and gloss finishes are designed to resist fading in the tropical sun, and the ‘GK’ badges add a touch of exclusivity. There are no extra graphics packs available.

The GK 350 launches as a single STD variant in India (no ABS/delete options or higher trims like ADV), powered uniformly by the 348cc liquid-cooled single-cylinder engine across all colours: standard kit includes dual-channel ABS, 5-inch TFT display, keyless NFC, TPMS, and 17-litre tank on a 188kg kerb setup. Uniform specs like 795mm seat height, 151mm clearance, and monoshock rear—no mechanical differences, focusing on accessibility in the premium 350cc space.

Value For Money And Pricing

The single STD variant is priced at ₹ 3,22,000 ex-showroom across India. EMI options start at ₹6,529 per month for five years at 9.7% interest, making it both accessible and premium. The Zontes GK 350 stands out for its feature-rich package at this price. It offers great value for money with segment-first features like keyless NFC, a 5-inch Bluetooth TFT, TPMS, dual-channel ABS, and riding modes, beating many rivals that cost the same or more.

The 348cc engine produces 39.33PS and 32.8 Nm, putting it on par with more expensive KTM models. The 17-litre tank gives a real-world range of about 450 km at 26-28 kmpl. Build quality is comparable to Japanese bikes, with few vibrations. However, the service network is still limited (now in over 20 cities), and resale value may be a concern since it’s a Chinese import. On the plus side, it comes with a 3-year/30,000km warranty and low maintenance costs (₹2,000 per service). Testers give it a 4 out of 5 for value, especially for tech-focused buyers who have a dealer nearby.

Key rivals to the Zontes 350R include the

1. KTM 390 Duke
2. TVS Apache RTR 310
3. BMW G 310 R
4. Royal Enfield Hunter 350
5. Husqvarna Svartpilen 401

The Zontes offers a better balance of features and price, but Royal Enfield leads when it comes to resale value.
