So far, we have refrained from spending $$$ to enhance the performance of the Beast. We likely will refrain in the future as well, since we don't ride all that aggressively and the Beast already outperforms every other cruiser extant. We can understand the draw, though. We think this need/desire comes under the general philosophy of "if gobs are good, then a whole lot more than that will be better still."
We trudge on.
