Recently Asked User Questions

Q. Which bike is the best Yamaha R15 V4 or Bajaj Pulsar NS200?
  • The Yamaha YZF-R15 V4 continues to be a trustworthy tool for riders looking to hone their track-riding skills. Of course, it is now a bit ergonomically friendlier and roomy enough for larger riders too. Additions like the traction control and quick shifter only amplify the bike’s sportiness. So, in our books, despite the price jump, the R15 V4 is a worthy proposition. On the other hand, the Bajaj Pulsar NS200 has soldiered through nine years of intense competition. As a result, pricing, features, and ease of use have ceased to be the bike’s strengths. The NS still puts up a strong fight in the BS6 era and is a perfect fit for those who like their bikes sporty and a little raw. Moreover, we would suggest you to take a test ride before making the final decision. Follow the link and select your desired city for dealership details.
Q. Which is better between Yamaha R15 v4 vs Yezdi Scramber?
  • The Yamaha YZF-R15 V4 continues to be a trustworthy tool for riders looking to hone their track-riding skills. Of course, it is now a bit ergonomically friendlier and roomy enough for larger riders too. On the hand, The Yezdi Scrambler is one attractive-looking motorcycle that packs equally impressive performance. And with its prices, even though it is a tempting proposition, we hope Yezdi addresses some glaring issues with the bike including quality and engine refinement. Moreover, we would suggest you to take a test ride for a better understanding of performance and comfort. Click on the link and select your desired city and brand for dealership details.
Q. I'm confused between, R15 V4 and Gixxer SF 250?
  • Both the bikes are good in their forte. While the Gixxer SF 250 offers a sporty riding experience, it isn’t an out-and-out sportbike. It does offer an affordable, and potentially more fun, an alternative to the Honda CBR250R, making it a great option for more mature riders. Whereas, Yamaha R15 V4 by sticking to its engine has a proven suite of abilities - everyday usability, unintimidating but exciting performance, and low ownership costs. So, the Yamaha R15 is more appealing and more capable than before, and despite the higher price tag still very worthy of being the first sportbike for the budding biker. Moreover, we would suggest you to take a test ride before making the final decision. Follow the link and select your desired city for dealership details.Read more -2021 Yamaha R15 V4 First Ride: Eternally Young?.
