I've narrowed my bike choice down to the '04 carburated Yamaha YZF600R and the fuel injected '04 Honda CBR600F4i. Which one do you think would be a better choice for an almost 30 yr old new rider who wants a bike that I'll be happy with for years to come. I'll be doing commuting and leisure riding (no track riding). The fuel injected F4i does seem to be a more advanced bike but it does come with a price premium of an extra $1600.00 over the YZF600R. But I would be willing to pay more if it's a way better bike. Thanks.
