Yes it is, I bought it third-hand, so I don't know all of it, but it was cutted and got a new "shoulder", witch was lited (make lighter); every modified was because the monster t was too heavy. Now it is 4 kilos without oil, wheel, so yes now it is maybe a little heavy, but the demo 9 is also heavy so not problem the centre of me is in the middle of two wheel, and of course it is so so strong. Guys told me, if you have a Boxxer, you will ride a bike on rear wheel.
