 Tenere 700 Speedometer & Odometer Accuracy vs GPS

My Tenere 700 speedometer indicates speed approximately +8 to +10% (allowable by industry regulations) above actual speed depending on tire & wear vs phone GPS, however the odometer is more accurate & within 1-2% of GPS readings & road mileage markers on level ground (industry regulations require more accuracy of odometers).  The Tenere 700 utilizes the front ABS ring for input, however, the bike's electronics likely apply different computations for speed & odometer.  

ABS Ring Correction

Sensor input for speed, & likely odometer, are determined from the front wheel ABS sensor ring. ABS rings with 42 slots (oem = 46 slots) are available to adjust speed display lower by approximately 10%, however, will likely adjust the odometer lower by the same 10% compensation & lower than actual mileage. Both front & rear ABS rings should be changed to ensure correct ABS operation & prevent error codes.  The Tenere 700 likely uses different computations for speed & odometer display, despite receiving input from the same sensor. Most automotive regulations do not permit odometer readings lower than actual.

Tenere 700: MIVV Dakar Exhaust & Carbon Heat Shield

MIVV Dakar Y.064.LDKX Exhaust + Carbon Heat Shield ACC.80.0 Why a New Exhaust? Yamaha opted for Dakar inspired styling & cost savings vs function with the design & location of the oem muffler for the Tenere 700 that positions it precariously low & outside the swingarm, attached to a welded on vs bolt on hanger that easily bends pushing the muffler into the aluminum swingarm with the slightest provocation (there have even been reports that some damaged bikes in the USA have been written off by insurance citing a bent frame). See  my blog article here  for additional info on the swingarm/muffler issue & several aftermarket T7 exhaust options. The oem wide muffler positioning also complicates the use of some soft bag & rackless systems & clearance with the hot muffler plus mandates that many luggage rack systems be detrimentally far away from the center line of the bike,  adding unnecessary width & undesirable handling dynamics at the back end.

    8 Day,  4,360 km (2,709 mile), 'Rideabout' - 2 Provinces, 5 States, 1 Provincial & 4 National Parks -  Aug 7-14, 2024 With each year, & officially a 'baby' senior at 66, motivation & ability to do the things I historically treasured become a plethora of balancing the increasingly disparate physical & emotional realities with the seductive biased recollections of my youth touring much of western Canada & USA, Baja/Central/Northern Mexico & 2 years in Texas via motorcycle...Bob Seger's "Against the Wind' echoes in my head 😎.  After having to cancel my Yukon/Alaska trip this June because of recurring back issues, & while no where near 100%, was in need of some throttle therapy & seized an opportunity. The ensuing journey is as much an exploration of my current abilities for a concentrated high mileage solo 1 or 2 week long 'rideabout' without much conditioning & lead up riding as it is about my accessorized ...

Tenere 700: Correct Fork Alignment - Floating Right Fork Needs to be Set Correctly on Axle to Obtain Equal Gap for Brake Caliper & Rotor - Service Manual Front Wheel & Tightening Torques - 'Everything Tenere' & Dave Moss Videos: Align Fork Legs Properly After Mounting The Wheel

Disclaimer: I am just a long time motorcycle enthusiast with moderate wrenching experience/skills (not a professional/Yamaha mechanic) & have compiled this info from others more experienced & knowledgeable as a reference based on my personal experience with my T7 that hopefully can help others. Fork Alignment & Right Fork Caliper/Rotor Position MUST Be Checked After Front Wheel Removal! T he T7 right front axle assembly is a floating design that, depending on several factors, may not correctly position the caliper & rotor for equal gap & can result in the rotor resting against the upper edge of the caliper...not a desirable situation if gone unnoticed. This information is NOT in the Yamaha Service Manual & can be an overlooked issue when changing the T7 front tire .. .the right fork's static/resting position is toward the outside on my T7, which incorrectly positions the inside edge of the caliper to make contact with the rotor ( has been posted by others ...
