i passed prac 5! now im waiting for RTT(riding theory test) this coming monday.if i pass,i can apply for PDL(prvisional driving license) and take prac 6.just a few more to go till i get my license! also,i need feedback to what i should do between this two options.

Option 1.
-Yamaha YZF r125
i really like this bike but it cost a bomb.i need to get roughly 10k for this bike.if i get this bike,i'll use it for 4-6 years.

or

Option 2
-Honda CBR125
this bike on the other hand cost ard 5-6k.if i get this bike,i'll use it for 2-3 years then change to a class 2a bike.

so what do you think? buy a bike that i really like and use it for a long time or just buy a cheaper bike and use it temporarily?
