Those would be nice options if i were building a weapon. But for a sometimes playbike/dirt tracker, I think a set of RM forks or similar will do very nicely. Once I get hold of a 500, I'll have a bit of a hunt around for what's available reasonably cheaply. I saw a pretty stock XL500 going awfully quick at canowindra last weekend, so clearly the old thumpers can go around a flat track OK. Just need to avoid anything remotely rough I think...
