any reason 200x wheels won't fit?

[havinnoj]

same bolt pattern, right?

all are the same, aren't they?

The stock 200x wheels will fit but you need to mount them inside out because the weld on the wheel center hits on the outer edge of the hubs.

86/87 200x wheels are 9" rims, probably same rims are stock that were for a 250r, no reason they shouldn't fit.
