[Hey, I must be the exception because I use my Tach frequently...and I have been riding 33 years (triumphs for 30). Yep, you don't need it but with my louder pipes I find myself putzin around at lower RPMs which isn't good and feel like the TBA is made to rev much higher. I didn't realize I wasn't even close to taxing the engine until I got the tach. It keeps me in the right range and also lets me know I have lots more room to go in a gear!!
I was exacty the same till i added 1 on mine. With the 18T sprocket i,m just cruising at 130km/h doing 4300 revs.
