I bought my 900 new in 2000 and it' been fine. service costs are much less than the 4V bikes and tyres etc last longer too. It's much quicker than you might think in the real world as well. But if you do still want more power then the new 1000 DS engine bike with a set of Termi's and a new chip has got to be close to 100bhp.
One thing though they are not a race bike on the road in the way the 916 series bike are, thats not always a bad thing though and they are still seriously good fun.
