Using a GPS I had over 70 mph with my KTM powered Blaster and my son's originally got about 50mph stock. I have since sprocketed slower, about 60mph and he is just a shade slower on top speed now.
No accurate numbers at the moment, sorry, but 60-65mph is probably right.
Still faster than any of the 750-800cc 4x4 quads I have ever run with.
Yeah it pulls from side to side at speed! Scary! Toe in has to be perfect and no slop in the front suspension.
Better to air the tires up too. Felt safer at 10 psi. Lengthened swing arm helped stability at speed too.
I am still running drum brakes and they are not so good at speed either.
Even with everything set up good, they still can go into a death wobble at those speeds.
I had a Raptor 660 before this Blaster. About 70-75mph top speed according to GPS.
Very prone to weird handling issues at those speeds. Too many close calls.
I like the Blaster so much better by-the-way...
