Best bang-for-buck modifications

[Xmcc99]

Hi, I just swapped out the stock air filter for a Simota Performance one .. must be the best £30 I've spent on a bike.
Gives it that extra bit of grunt that transforms the bike on the road.
Sounds better too,
And it's half the price of the K&N and DNA filters!
Soooooooo, what's the best bang-for-buck mod you've made on your RC390?...

Front brake pads. Huge improvement and cheap; plus super easy to install.

Can attest to the front brake pads... Bought some last week because of this thread and changed them last night. Holy crap, the difference is night and day.
