AJS Motorcycles has expanded its 125cc line-up with the new JS125-X, a learner-legal naked bike priced at £3,149 on the road. On paper, it looks like a straightforward value proposition: modern styling, full A1-legal power output, and a specification list that appears competitive for the money. The obvious question, however, is whether it offers enough substance to justify comparisons with more established rivals—most notably the Honda CB125R.
What You Get for the Money
At its core, the JS125-X uses a Euro 5+ compliant, four-valve, SOHC, liquid-cooled single producing a claimed 14.8bhp, right at the A1 licence limit. It’s paired with a six-speed gearbox and, according to AJS, capable of 97mpg, which would theoretically allow over 200 miles of range from its modest 10-litre tank. For learners and commuters, those figures tick important boxes.
The chassis setup also reads well at this price point. ABS is fitted at both ends, the seat height is a manageable 800mm, and suspension consists of upside-down front forks and a rear monoshock. Full LED lighting comes as standard, giving the bike a modern appearance that aligns with current naked-bike trends.
On specification alone, the JS125-X doesn’t look like a stripped-out budget machine. Instead, it aims to deliver the essentials most new riders actually care about: approachable ergonomics, low running costs, and contemporary styling.
The Honda Comparison
Visually, the JS125-X draws clear inspiration from Honda’s CB125R, a bike that has been on sale since 2018 and refined through significant updates in 2021. Elements such as the underslung exhaust, compact proportions, and sharply defined fuel tank shoulders make the resemblance hard to ignore.
Where the Honda pulls ahead is in refinement and technology. The CB125R benefits from a colour TFT display, high-quality Showa 41mm forks, and an IMU-managed ABS system, along with the backing of Honda’s extensive dealer network and long-established reputation for durability. At £4,799, however, it commands a substantial premium over the AJS.
Value Versus Expectations
This is where the JS125-X makes its case. It doesn’t try to out-engineer the Honda or match its electronics package. Instead, it focuses on delivering acceptable performance, modern looks, and key safety features at a significantly lower entry price. For a learner rider, the absence of a TFT dash or advanced electronics may be less important than affordability and ease of ownership.
That said, buyers should approach the JS125-X with realistic expectations. While the specification is competitive for the price, long-term factors such as dealer coverage, resale value, and perceived build quality are areas where more established brands typically hold an advantage.
Assessment
Viewed purely through the lens of value, the AJS JS125-X offers a compelling alternative for riders who want the look and usability of a modern naked 125 without paying premium-brand prices. It doesn’t pretend to be a CB125R replacement, but at over £1,600 less, it doesn’t need to. For budget-conscious learners and commuters, the JS125-X appears broadly proportionate to its price—provided buyers understand where the compromises lie.
