hello to everybody,, sorry for my english but i would like to know how much will it cost me aproximatively to upgrade my xt660x to 58hp.. mine is 100% stock now..

thank you so much

Just start small more fuel open air box free flow exhaust.�1,500 You could go big bore + change camshaft.

so it will cost me like 2000 to upgrade until 58hp... it will cost me more than a 660 smc ktm lol and still ktm has more hp right ?

True, but when the ktm is having is 20th service and it's second engine rebuild
The xt will have had a few oil changes and still be going strong
