The Jawa 42 FJ has been on sale for a few months now, carving out its own identity in the modern-retro segment. However, a new test mule spotted recently suggests that Jawa is cooking up a significant update for the 42 FJ. The most notable change? A switch from the signature dual exhaust setup to a sleeker, single-sided exhaust. And this isn’t just about aesthetics — this tweak could bring more than just visual differences.
Exhaust
Let’s start with the obvious change. Moving from dual to single exhausts might look subtle, but it has a real impact. The most immediate benefit is weight reduction. Losing an exhaust can trim down a few kilos, which in turn improves the power-to-weight ratio. That might sound minor, but every kilo counts when you’re pushing a small-to-mid capacity motorcycle.
Besides, less weight also translates to more nimble handling, especially around corners. If you’ve ever tried flicking a bike through a twisty section of road, you’ll know how a lighter setup can make a difference in how responsive and agile the bike feels.
Engine
Mechanically, the motorcycle is expected to remain unchanged under the skin. That means it’ll likely continue with the same 334cc, liquid-cooled, single-cylinder engine currently found in the Jawa 42 FJ. This motor produces a healthy 28.7bhp and 29.62Nm of torque, which is sent to the rear wheel via a six-speed gearbox. You also get a slip-and-assist clutch for smoother downshifts and reduced hand fatigue — a handy feature for everyday riding as well as occasional spirited rides.
Design
Aside from the exhaust change, the test mule still carries the same overall design language. It’s a good blend of modern touches and retro cues. You’ve got the round LED headlamp, teardrop fuel tank, and curved fenders — all of which stick to the modern-retro formula quite well.
That said, we might see some new colour schemes or graphics being introduced with this updated version. It would make sense for Jawa to offer some fresh styling tweaks to help visually separate the single-exhaust version from the current dual-can model.
Positioning
Now here’s where things get a little speculative. It’s not yet clear how Jawa plans to position this new version. The switch to a single exhaust might be part of a strategy to create a more affordable variant of the 42 FJ. Fewer components, potentially fewer features, and a slightly different look could allow Jawa to bring the price down.
Currently, the dual-exhaust Jawa 42 FJ is priced at around Rs. 2 lakh (ex-showroom). A stripped-down version could help attract a wider audience looking for style and performance at a slightly lower price point. On the other hand, this change might just be a running update for the existing model rather than a completely separate variant.
Here’s a quick comparison of what’s changing and what’s staying the same:
| Feature | Current Jawa 42 FJ | Upcoming Version (Expected) |
|---|---|---|
| Exhaust Setup | Dual Exhaust | Single-Sided Exhaust |
| Engine | 334cc, Single-Cyl | Same |
| Power | 28.7bhp | Same |
| Torque | 29.62Nm | Same |
| Gearbox | 6-Speed | Same |
| Weight | Heavier | Slightly Lighter |
| Design | Modern-Retro | Similar, with new graphics |
| Expected Price | Rs. 2 lakh | Possibly Lower |
Jawa hasn’t officially confirmed the launch timeline or the intent behind the test mule, but seeing it out in public means a reveal might not be too far away. Whether it’s a new variant or a running change, the updated Jawa 42 FJ seems to be aiming for better value and improved dynamics — a move that could work well in the competitive mid-capacity motorcycle segment.
