Ahhh, the ZRX. Was that the first killer "naked" bike? It is to me anyway.
We've got a heavily modded ZRX at the shop, nicknamed Brutus. Full stage 3 Muzzy bike that the PO let go for less than the cost of the Ti exhaust because he couldn't dial in the CV's after getting all of the engine work done.
Once we got the carbs right, it put down 128hp at the rear wheel. Despite att the go-fast goodies, it's still pretty tractable around town. My only complaints are the soft suspension, slow turn-in, and high hand-position - all of which can be rectified.
