Re: Looking for tips
The money you spend on mods is up to you. But this is how I always respond to these types of questions. Spend your money on quality gear (head to toe). Then get the ergos set, predominately getting the suspension tuned to your weight. I'd get tank grips as well, helps keep you connected to the bike. Inspect the bike top to bottom, noting anything that needs servicing. This might include fluids (brake, coolant, oil), new pads, inspect chain/sprocket etc etc. You see the trend here, save all the gimicky blingy mods for last. A stock bike running great beats a pretty bike running rough and dangerous.
My one tip is to spend a heck of a lot of time getting real familiar with the bikes brakes. Spend some time reading about proper braking including emergency braking and go out and practice it whenever you get a chance (once you get that rear brake sorted of course, haha). Crashes usually don't happen because of speed, they happen because the rider doesn't know how to safely stop from that speed.
Ride safe, and congrats on the new purchase.
