So on my 18 versys 650lt the speedometer is off by quite a bit. highway speeds 5 to 7mph. When I ride with my dad and his gold wing trike mine says we are going way over speed limit all the time and he tells me 60mph and I am usually at 65 to 67 following. even when we come to those digital speed detectors my bike never seems to be on. The bike is DEAD STOCK with factory gearing and tires. about 3000 miles. anyone else have bad accuracy issues and is there maybe a computer update or flash that could correct this! I will contact dealer but wondering if anyone else has experienced this.
