Iv just got my hands on a klx250sf 2010 and I'm looking to put some 50/50 tires and a rear rack I'm new to this bike thing just like to hear of some mods to do or anything to help me become a better rider

 

Congrats and welcome. I'm sure you'll find lots of mod ideas by just reading through the site. If it's your first bike you might want to consider a motorcycle safety course. It would probably be well worth your time and money.

 

Congrats on the new ride. As mentioned above, there are a LOT of good reads in the KLX section and being new to the street riding thing.....the MSC is a great course to see where you are at and will provide some good info to hone what skills that you may already have.

 

So mods Done to the 250s can be done to the 250sf they are kinda the same bike right?

 

Welcome to the forums. Take a look at the Kenda K270 tires. Not that bad on hard packed trails, and will wear real slow on the blacktop.

 

Oh and if you can, take a safety class. It will give you the basics of riding and surviving.
