Hey everyone. I’m sure this has been asked before. My son will be 6 in Jan. He’s 3’ 9””tall. He has ridden battery powered quads when he was 3 and loves it on my brute force ( passenger) Should I get a 50cc quad for him or a 90cc?

Or maybe a used 80cc?

I’m thinking the 50 would be good for now but I’m thinking he will outgrow it soon. Also I seen that the kfx 50 and 90 are same frame ?Is there much mods to buy for a 50cc to make it really wake up? I read the kfx 50 can only go 8mph. I see lots mods for lt80s

I assume these are the quads available. For 50cc there’s yfz 50, raptor 50, outlaw 50, predator 50, scrambler 50, lt50, kfx50, ds50

then I guess outlaw 70 and ds70 in between and lt80, kfx80, raptor 80

then 90cc there’s raptor, outlaw, predator, scrambler, lt, kfx, ds,trx

let me know if there’s more
