When i fitted gen5 fender (race bodywork) the story was:
Yes, fender is a bit wider (gen5 forks more apart). Fender did bend enough to fit. But then I replaced front wheel and when taking out axle the fender pulls forks apart (turning lower fork legs). This makes installing axle very uncomfortable. Ended putting spacers between fender and fork, problem solved.
Edit: Sorry this is vice versa, but same applies, I think you will need to bend fender out when installing axle.
Gen4 race: high spec.
Suzuki GSX1300R Hayabusa 2013: stock.
Kawasaki KX450F 2016: love it.
