Engineering excellence in the commuter segment is often measured by efficiency rather than raw power. The Suzuki Address UK 110 (DE1111) is a testament to this, featuring the proprietary Suzuki Eco Performance (SEP) technology. Unlike standard small-displacement engines, the DE1111 utilizes a specialized combustion chamber design that optimizes the ‘tumble flow’ of the air-fuel mixture, significantly reducing mechanical friction and achieving a remarkable balance between fuel economy and acceleration.
| Component | Specification |
|---|---|
| Engine Oil | SAE 10W-40 (API SH/SJ/SL/SM/SN JASO MA) – 0.65 L |
| Front Tire | 80/90-14 M/C 40P (2.0 bar / 29 psi) |
| Rear Tire | 90/90-14 M/C 46P (2.25 – 2.5 bar / 33 – 36 psi) |
| Battery | YTX5L-BS |
| Spark Plug | NGK CPR7EA-9 (0.8 – 0.9 mm gap) |
Technical Review: The Urban Specialist
The Suzuki Address UK 110, specifically the DE1111 generation produced between 2015 and 2022, was designed to dominate the dense urban landscape. Its 14-inch wheels provide a level of stability and pothole-dampening that 10-inch or 12-inch competitors lack, while its incredibly slim profile (only 665mm wide) allows for effortless lane filtering.
From an engineering standpoint, the fuel injection system is highly responsive, ensuring cold-start reliability—a critical factor for daily commuters. The 113cc air-cooled SOHC engine delivers peak torque at 6,500 rpm, which is perfectly geared for the stop-and-go nature of city traffic.
Maintenance Guide & Service Requirements
1. Lubrication System
The DE1111 requires a relatively small oil volume of 0.65 liters. Because of this low capacity, oil degradation occurs faster than in larger engines. MotoSpecsLab recommends using a high-quality SAE 10W-40 synthetic or semi-synthetic oil that meets JASO MA standards to ensure the longevity of internal components. Check levels every 1,000 km.
2. Electrical & Ignition
The ignition system relies on an NGK CPR7EA-9 spark plug. It is vital to maintain a gap of 0.8 – 0.9 mm to prevent misfires and maintain fuel efficiency. If you experience sluggish starting, check the YTX5L-BS battery; these compact units generally have a lifespan of 3-4 years depending on climate and usage frequency.
3. Tires and Chassis
Tire pressure is critical for both safety and fuel economy. The front 14-inch tire should be maintained at 2.0 bar (29 psi). For the rear, Suzuki specifies 2.25 bar (33 psi) for solo riding, but this should be increased to 2.5 bar (36 psi) when carrying a passenger to prevent sidewall deformation and overheating.
Editor’s Verdict
The Suzuki Address UK 110 NE – DE1111 remains one of the most reliable and cost-effective scooters on the second-hand market. Its mechanical simplicity makes it an ideal candidate for DIY maintenance, provided the owner adheres strictly to the specified oil and tire tolerances. It is a masterclass in functional minimalism.
