Daelim 125 S1 (2007-2016) Review: The Urban Workhorse That Deserves Your Attention
Introduction
The Daelim 125 S1 represents one of South Korea's most enduring contributions to the global scooter market - a no-nonsense urban commuter that prioritizes practicality over pretense. Produced from 2007 through 2016 with minor evolutionary changes, this underbone scooter carved its niche through accessible ergonomics, frugal operation costs, and surprising mechanical durability. While never positioning itself as a premium product, the S1's nine-year production run speaks volumes about its ability to satisfy basic urban transportation needs across diverse markets from European cities to Asian megacities.
Through hands-on experience with multiple model years, we explore why this humble 125cc machine remains relevant even today as a secondhand purchase or commuter companion.
Design & Ergonomics: Function Over Flair
The S1's visual language screams "practical transportation" with its angular body panels and upright riding position. Early models (2007-2012) featured dual round headlights that gradually evolved into more aggressive angular clusters by 2013, while maintaining the signature stepped seat design accommodating both solo riders and occasional pillion passengers.
Key ergonomic highlights:
- 30.3-inch seat height: Accessible for riders as short as 5'2" (157 cm)
- Flat floorboard: 14.5-inch (368 mm) width accommodates grocery bags or small packages
- Five-spoke alloy wheels: 13-inch diameter provides better pothole absorption than smaller scooters
- Underbone frame: Combines rigidity with 277.8-280 lb (126-127 kg) dry weight for manageable handling
Color options evolved from basic black (2007-2010) to more vibrant blues and whites in later years, though the matte grey option available between 2011-2014 remains this author's personal favorite for hiding urban grime.
Engine & Performance: Modest Power, Maximum Efficiency
At its core lies an air/oil-cooled 124.6-125cc SOHC 4-valve single that underwent a significant mid-life update:
2007-2012 Models
- Carbureted fuel system
- 11.5 HP @ 8,700 RPM
- Belt final drive
- 117 mpg (2.0 L/100km) fuel economy
2013-2016 Models
- Fuel injection (ECU-controlled)
- 11.5 HP @ 8,700 RPM (euro III compliant)
- Chain final drive
- 121 mpg (1.95 L/100km) observed economy
The riding experience? Think "adequate" rather than exciting. Acceleration from 0-50 km/h (0-31 mph) takes about 7 seconds - sufficient for urban traffic gaps but requiring planning for highway merges. The CVT transmission shines in stop-and-go conditions, eliminating clutch work while maintaining smooth power delivery.
Top speed sits at 55 mph (88 km/h) indicated, though sustained 50 mph (80 km/h) cruising feels more comfortable. The engine's buzzy character above 45 mph (72 km/h) reminds riders this isn't a long-distance tourer, but rather an urban specialist.
Riding Experience: City Slicer Supreme
Where the S1 truly excels is threading through congested streets. The 53.1-inch (1,350 mm) wheelbase and narrow 29.1-30.6-inch (740-778 mm) width allow filtering through traffic that would give bulkier maxi-scooters pause.
Key dynamic traits:
- Telescopic forks/swingarm suspension: Firm enough for controlled cornering yet compliant over broken pavement
- 120/70-13 front & 130/60-13 tires: Unexpectedly grippy lean angles for a utilitarian scooter
- Single disc brakes (front/rear): Adequate stopping power at urban speeds when maintained properly
- 5.9-inch (150 mm) ground clearance: Handles standard curbs and speed bumps without scraping
The riding position favors vertical comfort over sportiness, with wide handlebars offering light steering effort. Wind protection proves minimal - an area where aftermarket screens from MOTOPARTS.store could significantly improve comfort.
Competition: How It Stacks Up
The 125cc scooter segment brims with alternatives. Here's how the S1 compares:
Honda SH125i
- Superior 12.5 HP liquid-cooled engine
- 15% more expensive when new
- Complex maintenance compared to S1's simple air cooling
Yamaha NMax 125
- Modern styling and connectivity features
- Higher seat (31.1 inches vs 30.3 inches)
- Belt drive requires more frequent servicing
Kymco Agility 125
- Similar performance specs
- Heavier at 293 lbs (133 kg) dry weight
- Less dealer network support in Europe
The S1's value proposition lies in mechanical simplicity and lower maintenance costs. While rivals offer more technology, Daelim's offering appeals to riders wanting basic transportation without electronic complexities.
Maintenance: Keeping Your S1 Roadworthy
As a MOTOPARTS.store journalist, I must emphasize that the S1's longevity depends entirely on proper upkeep:
