If its your first bike, it might seem a bit expensive. You will come to find it is one of the cheaper bikes, especially since that price is for a brand new bike. Then again most in this displacement class are within a few hundred dollars of each other.
You can get used bikes for less, can get more engine for less, but obviously here, since you are just starting out, a small displacement bike is the right choice. I am just surprised you went new for your first bike. You know what they say about everyone drops their bike, would rather drop a used old bike than a new one, blah blah bla but meh, if you like it, buy it!
You wont know this till you actually have the bike and start riding, but yeah, no matter the price, it absolutely is going to be worth it. Its just money, all the fun you are going to have is definitely going to be worth seeing part of your wallet/checking account/savings account get smaller.
You know that saying "money cant buy happiness" ? Its a load of sh it. It can buy you a bike, and riding=happiness.
