## Content

The [Aprilia SXR 160](/bikes/aprilia/sxr-160) versus the Yamaha Aerox 155 is a comparison between two scooters that approach the Rs 1,30,000-1,45,000 premium segment from opposite directions. The SXR 160 is a maxi-scooter built around a premium safety and practicality brief: ABS, a ventilated disc with twin-pot caliper, a 7-litre tank, and a full digital display with USB charging. The Aerox 155 is a performance scooter built around a power brief: 15.3 PS from a liquid-cooled, variable-valve-actuation engine, Bluetooth TFT connectivity, and Yamaha's nationwide service network.

One important caveat before the comparison begins: reports indicate the Aprilia SXR 160 may have been discontinued in India. Confirm current stock availability with a Piaggio-Aprilia dealer before making a purchase decision based on this article.

## Price Comparison

| | Aprilia SXR 160 | Yamaha Aerox 155 |
|---|---|---|
| Ex-showroom Delhi | Rs 1,32,000 | ~Rs 1,41,400 |

The Yamaha Aerox 155 is approximately Rs 9,400 more expensive than the SXR 160. At these price points, neither is cheap - both ask for a meaningful budget premium over mainstream 125cc scooters. The Rs 9,400 gap matters less than what you get on either side of it.

## Specs That Matter

| Spec | Aprilia SXR 160 | Yamaha Aerox 155 |
|---|---|---|
| Engine | 160cc, **air-cooled**, 3-valve SOHC FI | 155cc, **liquid-cooled**, SOHC FI (VVA) |
| Max Power | 10.99 PS @ 7600 rpm | **15.3 PS @ 8000 rpm** |
| Max Torque | **11.6 Nm @ 6000 rpm** | 13.9 Nm @ 6500 rpm |
| ARAI Mileage | 35 kmpl | **43 kmpl** |
| Kerb Weight | 129 kg | **115 kg** |
| Fuel Tank | **7 litres** | 5.5 litres |
| Seat Height | **775 mm** | 795 mm |
| Front Brake | Ventilated disc, twin-pot caliper | Disc |
| ABS / CBS | **ABS** | CBS |
| Bluetooth | **No** | **Yes (TFT display)** |
| VVA | No | **Yes** |
| USB Charger | **Yes** | No |

The Aerox 155 wins on power (39% more), mileage (23% better), kerb weight (14 kg less), and Bluetooth connectivity. The SXR 160 wins on braking specification (ABS vs CBS, ventilated disc vs standard disc), fuel tank (7L vs 5.5L), lower seat height, and USB charging. The gap in braking safety hardware is the SXR 160's most significant technical advantage.

## Engine: Where the Aerox 155 Dominates

The Yamaha Aerox 155's 155cc liquid-cooled engine with Variable Valve Actuation produces 15.3 PS - the same basic engine family as the Yamaha R15 V4 and MT-15. VVA switches cam profiles at approximately 6,000 rpm for optimised low-end tractability and high-end power delivery. The result is an engine that performs meaningfully in real-world conditions from city traffic to open highways.

The Aprilia SXR 160's 160cc air-cooled 3-valve engine produces 10.99 PS. The additional 5cc of displacement cannot overcome the fundamental gap between an air-cooled 3-valve architecture and a liquid-cooled VVA unit. 15.3 PS versus 10.99 PS is not a marginal difference - it is 39% more power. In real-world riding, the Aerox pulls harder from any gear at any speed.

The SXR 160's 11.6 Nm of torque vs the Aerox's 13.9 Nm follows the same pattern. The Aerox has meaningfully more of everything that creates riding performance.

For riders who bought a premium scooter expecting premium performance, the Aerox 155 delivers it. The SXR 160 does not.

## Braking: The SXR 160's Definitive Advantage

This is where the SXR 160 makes its strongest case.

The Aprilia SXR 160 has a ventilated front disc with a twin-pot caliper and ABS. The Yamaha Aerox 155 has a front disc with a single-pot caliper and CBS. This difference matters in two specific ways:

**ABS vs CBS:** ABS (Anti-Lock Braking System) prevents wheel lock-up during emergency braking by modulating brake pressure. CBS (Combined Braking System) links front and rear brakes for proportional application but does not prevent lock-up. ABS is the safer system - in emergency stops on wet roads or during sudden hazards, ABS consistently reduces stopping distance and prevents loss of control compared to CBS. The SXR 160 is one of the very few scooters in India under Rs 1,50,000 to offer ABS on the front wheel.

**Ventilated disc with twin-pot caliper vs standard disc:** The ventilated rotor dissipates heat more efficiently during repeated hard applications - relevant for riders who brake frequently in heavy traffic or on downhill sections. The twin-pot caliper provides more even clamping force and better modulation than a single-pot unit.

For the safety-conscious buyer - particularly one who navigates heavy urban traffic with frequent emergency stops - the SXR 160's braking hardware is a legitimate reason to choose it over the Aerox 155.

## Fuel Economy and Range

The Yamaha Aerox 155's 43 kmpl ARAI rating is 23% better than the SXR 160's 35 kmpl despite the Aerox having 39% more power. The liquid-cooled VVA engine's efficiency advantage over the air-cooled unit is the primary reason. At real-world conditions, the gap narrows slightly but remains meaningful - approximately 38-42 kmpl for the Aerox versus 30-35 kmpl for the SXR.

Where the SXR 160 partially compensates: its 7-litre tank versus the Aerox's 5.5 litres. At real-world mileage:
- **SXR 160:** 7L × 32 kmpl ≈ 224 km per fill
- **Aerox 155:** 5.5L × 40 kmpl ≈ 220 km per fill

The per-fill range is essentially equal despite the SXR's lower mileage, because the larger tank absorbs the efficiency gap. For daily commuters who dislike frequent fuel stops, the SXR's 7-litre tank provides the same practical range as the Aerox while consuming more fuel per kilometre.

## Technology: Aerox 155's Clear Win

The Yamaha Aerox 155 features a Bluetooth TFT display with Y-Connect app integration - incoming call and message notifications, navigation hints, ride data logging, last parked location, and service reminders displayed on a colour screen. This is the most sophisticated connectivity package available on any scooter in this price range.

The Aprilia SXR 160 has a full digital (LCD) instrument cluster - a step up from the Storm 125's analogue twin-pod, but with no Bluetooth connectivity whatsoever. The USB charger is a practical convenience for device charging while riding, which the Aerox 155 does not offer, but it is not a substitute for the Aerox's connectivity suite.

At Rs 1,32,000 for the SXR 160 versus the Aerox's Rs 1,41,400, the Aerox's technology advantage costs Rs 9,400 more. For most buyers who value connected riding, that premium is well justified.

## Weight and Ergonomics

The Yamaha Aerox 155 weighs 115 kg - the Aprilia SXR 160 weighs 129 kg. Fourteen kilograms is a significant difference. The Aerox's lighter weight results in:

- Quicker direction changes and more responsive city handling
- Less effort when pushing, reversing, or parking
- Better power-to-weight ratio (the already-dominant power gap is further amplified by weight)

The SXR 160's 775mm seat height versus the Aerox's 795mm makes the SXR marginally more accessible for shorter riders. But the 14 kg weight penalty more than offsets the ergonomic benefit of the lower seat for most riding conditions.

The SXR's maxi-scooter seating position - more upright, more relaxed - is genuinely better for longer urban commutes than the Aerox's slightly more forward-leaning sport-scooter posture. For daily riding over 30+ minutes, the SXR 160's comfort is preferable. This is a real-world benefit that the spec sheet does not fully capture.

## Service Network

Yamaha's India service network - thousands of authorised workshops nationwide - ensures the Aerox 155 can be maintained effectively in metro cities, tier-2 cities, and beyond.

Piaggio India's Aprilia network is metro-concentrated. Delhi, Mumbai, Bangalore, Pune, Hyderabad, and Chennai have full authorised service; tier-2 coverage is limited. Beyond the network challenge, reports of the SXR 160's discontinuation introduce an additional concern: if Piaggio India has ended SXR 160 production, long-term spare parts availability may be affected even within the existing service network.

## Who Should Buy Which

**Buy the Aprilia SXR 160 if:**
- ABS braking is a primary safety priority - the SXR is the most affordable way to get ABS on a scooter in India
- Comfort and maxi-scooter ergonomics matter for your commute length
- The 7-litre tank and USB charging port are practical features you value
- You can confirm current dealer stock availability
- You are in a metro with Piaggio authorised service access

**Buy the Yamaha Aerox 155 if:**
- Performance matters - 15.3 PS vs 10.99 PS is a decisive gap that will be felt every time you ride
- Bluetooth TFT display and Y-Connect connectivity are important
- Fuel efficiency is a consideration - 43 vs 35 kmpl ARAI is significant over time
- Service network outside metros is a factor, or long-term ownership ease matters
- Resale value in 3-4 years is part of your buying decision

## The Honest Take

The Yamaha Aerox 155 is the stronger performance scooter by almost every conventional metric: meaningfully more power, better mileage, lighter weight, Bluetooth TFT, and Yamaha's unmatched service network. For the majority of buyers shopping in the Rs 1,30,000-1,45,000 scooter segment, the Aerox 155 is the more rational and capable choice.

The Aprilia SXR 160 makes a specific and legitimate case for one buyer profile: the safety-first urban commuter who values ABS above all else. ABS on a scooter at Rs 1,32,000 is genuinely rare in India, and the ventilated disc with twin-pot caliper adds further braking credibility. If you navigate heavy city traffic daily and emergency braking performance is your priority, the SXR 160's braking package is a real reason to choose it.

The discontinuation question complicates the SXR 160's case significantly. If buying a model that may no longer be in production, verify dealer stock, ask about extended warranty options, and consider long-term parts and service implications before committing. The Aerox 155, with no such uncertainty, is the straightforward choice for buyers who are not specifically optimising for ABS.
