I owned a 97 beast and it was amazing. Sold it for a good return.
A bit on the heavy side, the travel made up for it. The shortcoming for a while was the front fork. Once I learned to do a quick regrease every month, the bike was the most comfortable and reliable of any of my bikes. The key is release the brake pods, compress one leg at a time with preload to loosen the screws, remove legs, and unclip damping struts. Wipe grease onto dampers and bushes, and reassemble. Usually took me about 15 minutes, but buttery smooth.
A word to the wise, change out the plastic hydro crossover lines with braided, one kick with a shoe and breakage. Follow the easy swingarm bearing proceedure on the IDRIDERS Proflex site once a year, and you have it.
The beast was built to take a beating, and can handle 5 inch sliders with ease. There are a few more options for rear shocks as well, like the Risse Air shock, or adapting the latest SPV air shocks to the strut. You are very much limited with the 656.
I always liked the look of the beast and may pick up another for collecting.
