I don't own a bike yet and have been learning mainly on the 250cc LAMS bikes that the training centre owns. I will be off my L's in 4 months. I found a 2013 LAMS Duke 390 that I like and if I buy it now I will probably commit to riding it for a few years. The alternative is to wait for 4 months and buy a non-LAMS bike. Is it preferable that I build confidence and skill on a LAMS bike before moving up to a non LAMS bike? Or would it be better to stick it out for a few more months and go strait to a more powerful bike?
