No the Honda TRX 450R (Sport) ATV's do NOT come with reverse gear, regardless of the year. The 450 utility atv's do have reverse gear throughout all the years. Also the TRX400 EX comes with reverse and it is a sports model.
It could be a number of things.. Drasticly reverse gear could be just broken, or the reverse cable could have broken. I sugest you take it into a local ATV dealer to have a look
The official Honda website would have Honda ATV parts for sale or would at least have a list of dealerships that are in your area that sell Honda ATV parts.
You should post on a ATV forum. See related links for a Honda ATV forum. They will try to help you out.
