New motorbike

Unfortunately my moped was stolen but was found the night after. However, the thief had broken into the front and stole the bike's ignition

Unfortunately a few nights ago my moped was stolen but was found the night after. However, the thief had broken into the front of the bike and had stolen my ignition barrel and so not only is the bike very badly damaged, it will also not run. The parts and repair are more expensive than the actual bike and so it is not worth repairing the bike and i was advised to just go and buy a new bike. However with me being only 16 (nearly 17), even with the job i have, i cant afford to buy a new bike and since i will be 17 very shortly, im going to invest in a 125cc bike - the yamaha ybr 125
