Factors That Affect the Top Speed of the Jawa 42 Bobber

Following the success of Jawa Perak, Jawa Motorcycles released yet another bold and stylish bobber - the Jawa 42 Bobber. I certainly don't regret purchasing this motorcycle myself - it's every bit as awesome as I expected. Jawa 42 Bobber is hands down a great example of Jawa's principles of uniqueness, innovation, and quality.  

This bobber motorcycle is capable of reaching a top speed of around 130 km/h, which is more than enough for a retro motorcycle of its kind. However, the Jawa 42 Bobber's top speed depends on several factors, knowing which can help you zip through the roads faster.  

5 factors influencing the speed of your Jawa 42 Jawa 

While Jawa 42 Bobber is capable of clocking an impressive speed for a retro bobber motorcycle, its speed is influenced by a number of factors.  

1. The motorcycle's condition 

Timely servicing and maintenance are crucial to keep any vehicle in its optimal state. Failing to service your Jawa 42 Bobber regularly can take a toll on its performance and bring down its top speed. Similarly, you're likely to notice a drop in performance as your motorcycle gets older and the components begin to wear out.  

2. Road conditions 

The top speed you can reach on a Jawa 42 Bobber also depends on the condition of the road or terrain you're driving on. The more traction you get, the higher would be the Jawa 42 Bobber top speed you can achieve. You should also consider the gradient of the road into account - steep slopes slow down a motorcycle much more than flat ground.  

3. Wind resistance 

Air resistance has a significant impact on the speed of a vehicle, which is why aerodynamics plays a vital role. Your clothes, riding position, and any additional accessories installed on the motorcycle all matter when trying to enjoy the thrill of speeding along highways and open roads. As you might guess, riding against strong winds can slow you down significantly too.  

4. Weight 

Light vehicles are always easier to manage than heavy vehicles. Bear this in mind when making aftermarket modifications or equipping luggage attachments. Even the weight of the rider matters in this regard. Any extra weight forces your engine to work harder, which means the motorcycle needs more power to reach the same speed. At 185 kg, Jawa 42 Bobber is relatively lightweight. This is how the motorcycle boasts such steady performance even at high speeds.  

5. Tyre pressure 

Did you know that low tyre pressure can cause your motorcycle to go slower than usual?  

This is because a tyre with less air pressure has greater surface contact. The increased contact, in turn, applies more frictional force and tries to stop the motorcycle every second. For Jawa 42 Bobber, the ideal tyre pressure would be 23 psi and 28 psi for the front and rear wheels respectively.  

Endnote 

All three colour options of Jawa 42 Bobber flaunt a sporty look, be it the Jasper Red, Moonstone White, or Mystic Cooper Variant. Its performance, too, is just as sporty - all you have to do is adjust your riding habits to bring out the best your motorcycle can deliver. Now that you understand the factors that affect the top speed of your Jawa 42 Bobber, it shouldn't be much of an issue.
