Hi,
    The size mentioned by MZ Shop was 428 not 420, 428 is 1/2" x 5/16" chain.
Roller o/d for 428 chain is 0.335", ( 8.51mm ) roller o/d for 520 chain is 0.400", ( 10.16mm )
So it looks like the roller o/d, is the problem.
Yet the MZ gaiters for 125cc/150cc 13 28 014, which use's 420 chain, 0.305" ( 7,75mm ) o/d roller.
Will fit ( original factory part ) and run o/k, based on this no MZ gaiters should fit, confusing isn't it.
