I have a Ventura rack and pack to fit MTS1000 and also the smaller sport rack to use when you don't want the pack on. Good condition £50 plus postage
The pictures show the short rise sport rack, the higher pack rack , all fittings and straps and the bag itself which simply slips over the rack ...so easy to slip on and off and take with you. Great system. Can't remember how big the pack is in litres but bigger than average backpack, good for a long weekend. You can also get a second bag to zip to it. Check out Ventura website for further info.
