Introduction

The model "Aprilia - Sport City 125 One (2008-2011, ZD4SG)" is a compact and versatile scooter produced by the Italian manufacturer Aprilia between 2008 and 2011. It belongs to the Sport City series, known for its combination of urban mobility and sporty design.
The Sport City models were developed to meet the demands of city traffic while offering a certain level of dynamism and driving pleasure.
The Sport City 125 One represents an evolution of the original Sport City line and was specifically designed for riders seeking a nimble scooter with modern technology at an affordable price.

Development and Market Positioning

The Sport City series was first introduced in the early 2000s, with the Sport City 125 One considered part of the second generation of this model family.
While the first generation, such as the Sport City 125 (2004-2008), laid the foundation, the "One" variant introduced some improvements and adjustments from 2008 onwards.
Aprilia positioned the scooter in the mid-market segment, where it had to compete against models from Piaggio or Yamaha.
With its production period from 2008 to 2011, the Sport City 125 One falls into a phase where Aprilia increasingly focused on the growing market of 125cc scooters, which were particularly popular in Europe among younger riders and commuters due to their A1 license class.

Technical Specifications

The Aprilia Sport City 125 One is powered by a single-cylinder four-stroke engine with a displacement of 124 cc.
This engine features electronic fuel injection and is liquid-cooled, ensuring consistent performance and good heat dissipation even during longer city rides.
The power output is about 11 kW (15 hp) at 9,000 rpm, providing solid acceleration and a top speed of around 100 km/h for a scooter of this class.
The vehicle is equipped with a continuously variable transmission (CVT), which ensures easy handling and smooth power delivery.

Chassis and Brakes

The chassis consists of a hydraulic telescopic fork at the front and a single adjustable shock absorber at the rear, giving the scooter a balanced mix of comfort and stability.
The braking system includes a 260 mm diameter disc brake at the front axle and a 140 mm drum brake at the rear, ensuring reliable deceleration even at higher speeds.
With a weight of about 131 kg (dry) and a wheelbase of 1,360 mm, the Sport City 125 One offers good maneuverability, making it particularly suitable for city traffic.
The tires, sized 120/70-15 at the front and 130/80-15 at the rear, emphasize the sporty character and provide sufficient grip.

Design and Color Variants

The Aprilia Sport City 125 One was available in several color variants, which could slightly vary depending on the market and production year.
Common paint options include "Nero Aprilia" (Black), "Bianco Glam" (White), and "Grigio Titanio" (Titanium Gray).
These colors highlighted the modern and urban look of the scooter.
Information on special editions is scarce, and there are no clear indications that Aprilia released limited editions or special equipment variants for the Sport City 125 One.
The focus was rather on a uniform series production aimed at functionality and a broad customer base.
However, regional markets or dealers might have offered individual customizations, which do not qualify as official special editions.
