A great first mod for new riders, whether you fit it yourself or get a shop to do it before picking the bike up, is crash protection. That way if the worst happens and you drop your bike, have a small off, or someone else knocks it over, you’ve generally greatly reduced the damage and any repair costs.
Especially on road bikes replacing painted scratched panels, cases and similar can be pricey, and if it’s your pride and joy, you’re less inclined to just leave it damaged. With the right crash protection you might just end up with some light scuffing on the protection and maybe your bar-ends if you’re lucky.
