Ya it's not the highest end kit but that's a lot of cash for the kit stuff especially for a bike that may end up on the ground. I hear it's a really nice setup and it should be for the cash. I bought a few kit parts from the states for less than 1/3 of the price up here so maybe contact someone down there.
If breaking expensive parts is a worry for you then a $400 throttle kit would be the last of my worries. I've got around $30, 000 into the bike. I've already crashed it twice....after a crash I'm looking at the parts that cost me $1000-2000 each to see if they are ok before I even worry about my injuries
And although very possible a throttle housing isn't something I've ever broken in a crash. And I've done quite a bit of crashing lol
