Just completed some Yamaha new model training which included the 530 T-Max and the Xentor 125.
Some of you may be interested in some info on the 530.
Bore size up to 68 from 66 mm.
Improved cooling from re-designed cylinder head and cylinder.
Due to complaints of 'rattling variators' new model has 8 sliders over 4 from the older models.
Secondary sheeve (pulley) is now chrome plated.
Plastic! inlet manifolds.
A bit about the belt.
This runs very very tight with no discernable free-play at all.
There are no adjustment marks,however the ends of the swinging arm and the wheel adjustment blocks are machine finished to allow accurate measurment. The limit in difference is only 0.5 mm.If you get it wrong you will hear horrible noises from the belt!
The rear pulley is not round but pentaganol so therefore has to be placed in the right position to make adjustments to the belt.Imagine a line drawn through the centre of the front sprocket going through the centre of the rear wheel spindle.One of the pulley nuts needs to be on that line (in the 3 o'clock position looking from LHS) I hope you can understand that?
There is a special tool to measure the belt tension but it's not cheap! I reckon on £200 at least.Nice one Yamaha

The Xentor 125 looks interesting,sitting as it does between the Vity and the X-Max 125.It costs approx £3,000.
Be warned,it has bugger-all storage under the seat.Well maybe you can get your sandwiches under there.
For the first year you get free top-box and screen.
It has the Yamaha Unified braking system (linked brakes)
Interestingly,the Xentor 125 is one of the first units to take advantage of lap-top diagnosis as Yamaha are dropping the 'on-board' system due to costs I expect.
