Plenty of american parts dealers are much cheaper than over here until you add the taxes.
Think it runs at about 21.5% all in now.
Think its 17.5% VAT plus about 4% import duty?
Could be wrong though.
Motowheels are very good over there and have dealt with a few times, even sent me new seals for the lutch slave cylinder when they started to leak after a month on the bike.
They have a sales section where theres quite a few deals to be had too.
