👋 Introduction

Market Niche:

The Suzuki GSX250F Across was positioned as a versatile sport-touring or standard motorcycle, likely aimed at riders seeking a balance of performance, comfort, and everyday usability. The 4-cylinder engine configuration, while less common in the 250cc class, suggests a focus on smooth power delivery and refinement.

Competitors:

Competitors in the 250cc sport-touring/standard segment during its potential production era would have included models like the Honda CB250 series, Kawasaki ZZ-R250/GPX250R, Yamaha FZR250/TZR250 variants, and potentially others depending on the specific market and year.

Distinctive Attributes:

The primary distinguishing feature of this manual's target vehicle is its 248cc 4-cylinder, water-cooled, DOHC engine, which would have offered a smooth, high-revving powerband. This configuration was relatively unique in the 250cc class, often favoring twin-cylinder designs for simplicity and cost.
