                                        All three Brute Forces’ feature 
                                        dual front disk brakes and on the rear 
                                        it features a sealed and enclosed braking 
                                        system | 
                                
                                If the engine braking isn’t enough for you 
                                to slow your roll, you can apply both the front 
                                and rear brakes with the pull of the right lever. 
                                All three Brute Forces’ feature dual front 
                                disk brakes and on the rear it features a sealed 
                                and enclosed braking system. This was designed 
                                insure maximum ground clearance and also protect 
                                the rear brakes from mud, dust, and other debris. 
                                With an exception of the straight axle on the 
                                Brute Force 650 4x4 the independent rear suspension 
                                models have a ground clearance of almost 10 inches 
                                making easy work of any obstacles in the path 
                                of the Brute Force 650 4x4i and 750 4x4i. 
                                
The major difference between the Brute Force 
                                  650 4x4, Brute Force 650 4x4i, and the Brute 
                                  Force 750 4x4i is the “i” in its 
                                  name; the “i” which stands for independent 
                                  rear suspension. The independent rear suspension 
                                  makes for a much smoother ride than the standard 
                                  straight axle of the old days.

                                        the "i" model Brute Force machines 
                                        use an independent rear suspension feature, 
                                        which smoothes out the ride and also creates 
                                        more ground clearance for getting over 
                                        larger obstacles | 
                                
                              The “i” models handle much better 
                                  in rugged terrain compared to the standard straight 
                                  axle featured on the Brute Force 650 4x4. The 
                                  independent rear suspension not only helps smooth 
                                  out the ride but it also creates more ground 
                                  clearance to get over large obstacles. The “i” 
                                  models also feature front and rear double a-arms 
                                  with five way adjustable shocks to further fine 
                                  tune your ride.  
                                
The engine displacement is another distinct 
                                  difference between the Brute Force 650 4x4, 
                                  650 4x4i, 750 4x4i. The two 650’s share
