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?...
