Key Points Summary

  • Motonews League Overview

    This is the final and fourth episode of the Motonews League, a four-part series comparing motorcycles, with previous episodes available for viewing in a playlist.

  • Featured Motorcycles

    The Kieve K249N and Dominar 250 are selected for comparison due to their attractive and closely matched technical specifications, prompting a detailed performance analysis.

  • Kieve K249N Technical Data

    The Kieve K249N is a 249cc, 4-stroke, four-valve engine producing 24 horsepower at 9750 rpm and 22 Nm of torque at 7500 rpm, with an approximate weight of 151 kg.

  • Dominar 250 Technical Data

    The Dominar 250 delivers 27 horsepower at 7500 rpm and 23 Nm of torque at 6500 rpm, achieving maximum horsepower and torque at lower engine speeds, and has a dry weight of 180 kg.

  • Drag Race Performance

    In initial drag races, the lighter Kieve K249N was initially ahead, but the Dominar 250 consistently managed to catch up and overtake, especially as speeds increased, demonstrating superior sustained acceleration.

  • Dominar's Performance Edge

    The Dominar's ability to achieve peak horsepower and torque at lower RPMs, combined with its long-geared gearbox, allowed it to roll and gain significant ground, making a noticeable difference in sustained acceleration.

  • Kieve K249N Gearbox Characteristics

    The Kieve K249N features a power-shift gearbox with short gear ratios that enable quick engine revs but ultimately sacrifice top speed.

  • Dominar 250's Top Speed and Acceleration

    The Dominar 250 may not have sharp initial acceleration but provides powerful and beautiful acceleration in higher gears, likened to a 'nitro' boost, effectively closing gaps and passing competitors.

  • Braking System Analysis

    The Kieve's front brake is very good, whereas the Dominar 250 appears to have an assembly problem with its brakes, performing less sharply than other models like the Apache 200 or Zontes, despite its higher weight.

  • Kieve K249N Tire Modification

    The Kieve K249N's first series featured a 15-inch rear tire, which was subsequently reduced to 14 inches to improve handling and mitigate a 'muddy underfoot' sensation.

  • Overall Series Conclusion

    Across the 5-6 videos in the Motonews League collection, the Dominar 250 engine consistently finished first, highlighting its superior overall performance despite its weight.

  • Viewer Engagement

    Viewers are encouraged to visit the playlist for previous episodes, subscribe to the channel for more videos and insights, and leave comments, particularly for discussions about Duke motorcycles or gearboxes.

  • Future Content Tease

    The presenter plans to acquire a new engine, possibly a Duke, for future challenges against the Dominar 250, and may consider selling their current motorcycle.

Bajaj engineering, spanning nine years, delivers a motorcycle that, despite its weight, gearbox, and tire size, performs exceptionally well, demonstrating an impressive overall package.
