Tenere 700: JT Sprockets JTR1591.15RB 15 tooth Front & JTR1876.44 44 tooth Rear Sprockets & DID 525VX3 Chain

 JT Sprockets JTR1591.15RB 15 tooth Front & JTR1876.44 44 tooth Rear Sprockets

At 28,852 km the oem chain is stretched close to the maximum tolerance & ready to retire & wanted to tweak the gearing slightly shorter from the 16/46 = 2.875 ratio or 6.64% taller than the oem 15/46 = 3.066 that I have been running since 6,900 km or 4,287 miles, which, imho, better compliments the T7 CP2 powerband for average pavement/adventure/FSR non-technical use than the relatively short 3.066 oem gearing, which tends to encourage short shifting in everyday riding & elevates rpm higher than optimal during hwy speeds. 

I'm changing to 15/44 = 2.933 which is 4.53% taller than the oem 15/46 = 3.066 gearing or the equivalent of a 1 tooth change from the 16/46 = 2.875 currently used & 2 teeth from the oem 15/46 providing the following benefits: 

  • 2.01% increase in torque vs 16/46 = 2.875 gearing
  • the smaller front & rear sprockets vs the 16/46 combo will position the rear wheel further rearward shifting weight bias to the rear & increasing stability
  • the smaller diameter sprockets will increase clearance at the countershaft & rear sprocket vs 16/46 sprockets

JT sprockets makes rubber cushioned 15 & 16 tooth counter shaft sprockets to match the oem, but don't make a 44 rear sprocket in the oem black anodizing. I won't be able to verify how it feels/performs until the bike is insured next spring, but based on 6,900 km or 4,287 miles of use with the oem 15/46 & 19K+ km or 11,800+ miles with the 16/46 gearing ridden in a variety of terrain & circumstance I'm hopeful that this may be the unicorn gearing for my type of riding by increasing torque output slightly vs 16/46 gearing without much detriment to high speed rpm, while still being 4.53% taller gearing vs the oem 15/46.


DID 525VX3 Chain

I considered a 520 chain conversion from the oem 525, but had already bought a 130 link DID VX3 525 chain (oem = 122 links) on a 40% sale a year ago & sourcing a 520 44 tooth to be challenging, so decided that the benefits of the smaller chain & sprockets weren't worth it this time around.

Tenere 700: MIVV Dakar Exhaust & Carbon Heat Shield

By

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 ...
