If straight-line speed is your priority, the 450SR (SS) takes the lead. With 8 HP more than the YZF-R3, it offers a more spirited ride that will be noticeable on highway overtakes or track days. Both bikes share a similar footprint on the scale, with only a negligible 1kg difference between them, so handling characteristics will depend more on center-of-gravity than raw weight. Riders with a shorter inseam should lean towards the YZF-R3. Its seat height is 15mm lower than the 450SR (SS), making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the 450sr offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
