Here is my TPC. It started as a 2007 TRX450ER $3200, and a 2006 CRF450R $2600, and they were both in great shape. Sold the leftover bike for $1000, and quad parts for $800. With the work Bill did and parts I bought from him I was into him for $3216. So now I have a great trike that cost me a total of $7555 . Man is it worth it too.
