the mts 620 will have an aptc clutch, which has 14 or so friction plates. the 750 engines ended in 2002 and had a normal style wet clutch and 8 or 9 friction plates. it's either one or the other.

looks like the mts620 manual shows 11 plates for the aptc. it definitely has more than the older normal style wet clutch.

yeah, it smelt a bit like sellers bullshit to me too, but you never know. maybe it has 88mm pistons in it?

i would check them every 10 - 12,000km, which is 6,000 - 7,500 miles i think. up to you. they do settle down over time if the collets are not replaced, and you can extend the interval.
