R 12 2026 vs XDiavel V4 2026

Riders with a shorter inseam should lean towards the R 12. Its seat height is 16mm lower than the XDiavel V4, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the xdiavel-v4 offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
