[kamikaze]

Hey guys building my 450r for some weekend fun to go out riding with a few mates 500cc ltr, 65hp banshee ect

I wanted to know what the biggest stroke/cc I could go without needing case mods
And what sort of HP I'm looking at

Coming from a 70hp banshee the yfz handles great but is gutless in comparison

The bike is just for play/dune riding

Thanks for any help
