Q. R15V3 VS R15V4 Which is better?

Both bikes are high-quality and reliable. The V4 comes with the latest electronics, a more streamlined body, and other updates.As an owner of the V3 BS4 Non-ABS, I don’t consider the V4 to be a major upgrade over the V3. If you enjoy feeling the engine's power, you’ll appreciate the V3. Its stock exhaust is louder than the V4’s, and the engine is one of the most powerful in its segment, as well as across the entire Yamaha R15 lineup.

Absolutely v4 because it has better aerodynamics than the v3 and better initial torque.

When it come to the ride feel nothing beats the v3 , but the v4 has more tech than it
