What's the BEST mod you've put on a bike?

As a counterpoint to the other thread, what's the best money you've spent on your bike?I'm personally of the opinion that 90% of common mods are largely a complete waste of money, but there are some really valuable ones. For me?MT07 got an R6 throttle tube. Much shorter throw from closed to WOT made the bike vastly more fun to ride. $20. Best "performance" upgrade I've ever done on a bike - and it doesn't actually even increase performance.Quality aftermarket seat. If you ride any distance on a non-touring bike, the comfort these can bring make it really worth the cost. Not glamorous, and typically not a significant visual improvement, but it makes long rides way more pleasant.Frame/axle sliders/crash bars. Shit happens, and these can hide the evidence of your mishap. Fairings are fucking expensive. via /r/motorcycles https://www.reddit.com/r/motorcycles/comments/dqfrxh/whats_the_best_mod_youve_put_on_a_bike/?utm_source=ifttt
