The Benelli TNT600i is a middleweight naked streetfighter defined by one rare and special trait in its class: a four-cylinder engine. While most rivals in this price band use single or twin-cylinder motors, the TNT600i offers the exotic, high-revving character of an inline-four in an affordable naked package. Its aggressive headlight, muscular sculpted tank and stubby exhausts give it genuine street attitude. For riders who crave the sound and top-end rush of a four-cylinder without the cost of a litre-class superbike, it holds a unique appeal.
The TNT600i is powered by a 600cc inline-four DOHC water-cooled engine making roughly 80 to 85bhp at around 11,500rpm and about 54Nm at 10,500rpm, driving through a six-speed gearbox. The character is defined by a screaming top end, with the engine coming alive as the revs climb, delivering an intoxicating soundtrack that is the bike’s signature draw. Low-end torque is modest compared with twins, so it rewards riders who enjoy revving it out. It is a heavier bike, which suits its highway-cruiser-meets-streetfighter nature more than tight city work.
This bike is aimed at enthusiasts who specifically want an inline-four experience and the drama it brings, rather than the most practical everyday commuter. It suits riders who love spirited highway runs, revving through the gears and standing out with a distinctive exhaust note. Those upgrading from twins who crave a smoother, higher-revving character will enjoy it. It is less suited to riders who prioritise low-speed tractability, light weight or maximum fuel efficiency in city traffic.
Braking is handled by twin front discs and a rear disc, with ABS available for added safety on later versions. Inverted telescopic front forks and a rear hydraulic monoshock keep the bike stable at speed, complementing its highway-focused nature. The four-cylinder’s smoothness at high revs reduces vibration fatigue on long rides. Riders should note the bike lacks the modern electronic aids like traction control found on some newer rivals.
The TNT600i keeps its focus on mechanical character rather than gadgets, offering an informative instrument console, aggressive streetfighter styling and that headline inline-four engine. Under-seat or side-mounted exhausts and a well-sculpted tank define its look. It is relatively light on modern electronics, staying true to its analogue-feeling, engine-led appeal. For buyers chasing four-cylinder charm at an accessible price, the core package is the attraction.
A four-cylinder engine has more components than a twin, so servicing can be a little more involved and buyers should ensure a capable Benelli service centre is within reach. Parts availability and network coverage are important to confirm before purchase, as they are smaller than mainstream brands. Regular valve checks, chain care and scheduled service keep the four running sweetly. Budgeting for slightly higher upkeep than a twin is sensible.
A high-revving inline-four is thirstier than a twin, so real-world mileage typically sits near 18 to 20kmpl, meaning higher day-to-day fuel costs. The trade-off is the character and sound that no twin can match. Tyres, chain upkeep and periodic service add to running costs, which are higher than single or twin rivals. For enthusiasts, the experience justifies the extra expense.
The TNT600i is offered as a single-variant inline-four naked, historically priced in the mid-to-high six-lakh range (ex-showroom), positioning it as an affordable route into four-cylinder ownership. Availability has varied over time, so checking current dealer stock and pricing in your city is advised. Its four-cylinder engine remains its biggest differentiator at the price.

Yes, with the right care. The inline-four is characterful and durable when serviced diligently, but four-cylinder engines need more attention than twins. Long-term ownership depends heavily on access to a capable Benelli service centre for parts and periodic maintenance.
It is best on open highways and spirited rides, where the four-cylinder engine shines. It can commute, but its weight, modest low-end torque and higher fuel use make dense city traffic less comfortable, so it suits enthusiasts more than pure commuters.
It is relatively more expensive to run and maintain than a twin. The four-cylinder uses more fuel, and servicing is more involved with more components. Budgeting for higher fuel, tyre and service costs is important before buying.
If you specifically want an inline-four experience at an accessible price, the TNT600i is unique in its class. Cross-shop the Kawasaki Z650 and CFMoto 650 twins if you prioritise efficiency, low-end torque or service reach. Choose the TNT600i purely for four-cylinder character.
Benelli generally recommends servicing at regular intervals of a few thousand kilometres or roughly every six months, whichever comes first. A four-cylinder benefits especially from disciplined, on-time servicing including periodic valve checks.
With diligent servicing and care, the TNT600i can last well over a decade and 70,000 km or more. Because it is a four-cylinder, longevity depends even more on timely maintenance and access to genuine parts.
