Ducati’s 400SS Junior is an enigmatic package that defies expectations. Despite its diminutive size, it shares a chassis with the 750SS, making it virtually identical in weight and handling. However, beneath its sleek lines and SS-inspired ergonomics lies a powerplant that’s essentially a sleeved-down version of the 750SS.
The 398cc Desmo V-twin engine may have been designed to meet insurance-friendly regulations, but it feels like an afterthought, struggling to muster the same level of urgency as its larger counterparts. With a subpar power-to-weight ratio and a conservative gearing strategy, the Junior can feel sluggish in certain situations.
Despite these limitations, the 400SS Junior remains a tantalizing prospect for those who value style over substance. Its beautifully balanced ergonomics make it an absolute joy to ride, with adjustable pegs and handlebars that cater to riders of all shapes and sizes. Whether you’re leaning forward in a compact position or stretched out in a more relaxed pose, the Junior’s riding experience is genuinely unique.
The Ducati 400SS Junior is a bike that will leave you questioning its very existence – brilliant yet underwhelming at the same time.
