ok just want to know.

Thanx

if your belt is listed as 729x18x30 it's 729 long, 18 wide, 30 angle and about 8-9 mm deep. 2 deg angle difference makes no issue when belt wear in and sits into pulleys

There are all sorts of belt sizes advertised for a scoot. For my ZX I have seen 669, 729, 732 and 743mm belts, all for the same scoot. My next buy will be either a 743 or 748 just to try and see how it goes. My 732 still didn't go to the outer edge of the rear pulley.

Forgot to add, the stock belt is around 724mm.

Thanks for the info, thought 30mm seemed a bit wide 

Going to order 5g rollers and recheck the belt at the weekend anyway now when I fit the rollers.

sidthesloth, is it going all the way up on the front pulley?
maybe try 732 x 18.5
or 740/743 x 18
