The Jawa 42 FJ has already made a mark in the neo-retro motorcycle segment since its launch, but it looks like the brand is working on a new variant. A test mule has been recently spotted, and the most notable change is the shift from a dual-exhaust setup to a single-sided exhaust. This update could bring several performance and pricing implications for potential buyers.
Lighter Setup
One of the most obvious benefits of switching to a single exhaust is weight reduction. Dropping one exhaust pipe should shave off a few kilos, making the motorcycle slightly lighter. This small change could have a positive impact on the bike’s overall power-to-weight ratio, potentially leading to crisper acceleration and better fuel efficiency.
Less weight also means improved agility. Whether you’re zipping through city streets or leaning into corners on weekend rides, a lighter bike just feels more responsive — especially for a mid-capacity motorcycle like the 42 FJ.
Engine and Specs
In its current form, the Jawa 42 FJ is powered by a 334cc, liquid-cooled, single-cylinder engine that delivers 28.7bhp and 29.62Nm of torque. This engine is paired with a six-speed gearbox and benefits from a slip-and-assist clutch, which helps in smoother gear shifts and reduces effort during heavy traffic riding.
It’s not yet clear whether the engine will get any tuning updates for the single-exhaust version, but even with the same output, the reduced weight could make it feel a bit livelier on the road.
| Specification | Jawa 42 FJ (Current) |
|---|---|
| Engine | 334cc, single-cylinder |
| Power | 28.7bhp @ 7,000rpm |
| Torque | 29.62Nm @ 5,000rpm |
| Gearbox | 6-speed |
| Clutch | Slip-and-assist |
| Exhaust Setup | Dual (testing single) |
Possible Positioning
Another possibility is that the single-exhaust version could be introduced as a lower-spec or more budget-friendly version of the 42 FJ. If this turns out to be the case, we could see a few feature deletions to bring the cost down. This version might appeal to buyers who want the same performance and styling but are willing to sacrifice a few extras for a better price.
Currently, the Jawa 42 FJ is priced at Rs 2 lakh (ex-showroom). A more affordable variant with fewer features and a lighter build could help expand the bike’s reach to a wider audience.
Design Tweaks
Visually, the prototype doesn’t appear to have undergone any radical changes apart from the exhaust. It still features the modern-retro aesthetic that defines the 42 FJ — round LED headlight, tear-drop fuel tank, curved fenders, and a clean silhouette.
However, to help differentiate this version, Jawa might introduce new colours or graphics. These visual changes would also help freshen up the lineup without requiring a complete design overhaul.
What It Means
This move by Jawa could be strategic. With competition growing in the modern-classic segment, having multiple variants of the same model at different price points allows the brand to cater to different rider profiles — from new buyers to seasoned enthusiasts.
If the brand manages to retain the core characteristics while making it lighter and slightly more affordable, the single-exhaust 42 FJ might just hit the right balance between performance and value.
