450SR (SS) 2024 vs RC390 2024

Both bikes share a similar footprint on the scale, with only a negligible 4kg 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 450SR (SS). Its seat height is 29mm lower than the RC390, 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.
