I have a 2013 Triumph Tiger 800XC motorcycle. It is a major pain in the rear to get to the air filter. Six pieces of plastic, remove the tank and hold it with one hand as I clumsily disconnect several electrical connectors and fuel lines with dusty and increasingly brittle obscure mechanical plugs, then the air filter box is exposed. Haven't broken one of these things yet, but it's a matter of time as they're approaching 10 years old.
This bike is meant to be ridden off pavement, but a shortcoming of it is how difficult it is to inspect or clean/replace the air filter.
Evidently there is an aftermarket modification for the bike that I've only just learned about. UNI makes a "pre-filter." It replaces the under-seat air intake snorkel before the air hits the under-tank air filter, with a dirt-bike style oiled foam filter.
https://cjdesignsllc.com/product/uni-triumph-tiger-800xc-2011-14/The intent of the mod is to extend the service interval of the under-tank air filter, by making this under-seat "pre-filter" do the lion's share of the work. And by being under-seat, it is far easier to access, remove, clean, and replace than the under-tank filter.
However, I question whether this would function as an air restriction and end up robbing the bike of air intake, causing it to run rich or air starved. What does the braintrust here think?
I've been stewing on replacing this Triumph for awhile, and even have a down payment on an Aprilia Tuareg 660 as a potential replacement, waiting on one to come in at the dealer for a test ride. Two factors that drive me to look at the Aprilia as a replacement are ease of air filter access, and the Aprilia has cruise control. If I can resolve the air filter access problem on the Tiger, and add an aftermarket throttle lock like the Kaoko or Atlas, I can potentially stave off buying a new bike for awhile longer. Then again, the Aprilia is about 75 pounds lighter than my Tiger and also has a lower center of gravity due to its fuel tank design, which has a lot of attraction for how much I ride on uneven terrain.
