    BMW R18 battery

    I was addressing your statement that lithium batteries are at the bottom of the reliability list. All 3 of your BOS failures on lithium ion batteries? LiFePo4 batteries do not have a high failure rate for the BOS or any other component, you must just be very unlucky.

    BMW R18 battery

    There is a big difference between lithium ion and lithium IRON batteries. Lithium iron are smaller, much lighter (Under 2 lbs vs 10), self-discharge at a very low rate, are not affected by the vibration of a bike, do not overheat like lithium ion, and last forever. I’ve used Shorai batteries in...

    Thinking of an R18

    Being a rider for 60 years I have ridden and owned many bikes. I have absolutely loved many of them, and others not so much. There is so much right about my R18, and so little not right, that it is maybe my favorite bike overall. Of course, no bike meets “the best” criteria for every rider but...

    Wimpy Horn Replacement

    Try the Clarton horn, much louder, very easy to install, readily available, and only @ $25

    Wimpy Horn Replacement

    I did this Clarton horn replacement today, took less than 10 minutes and it fit perfectly. I pointed the horn between forward and down, at about a 45 degree angle so it would face as forward as possible and still drain any water easily. The difference in tone and volume was AMAZING! Best $30...

    Unit Garage Exhaust

    I don’t think they’re available in any other finish. When they touch depends to some degree on the angle you mount them.

    They do have db killers which you can leave out if you want, they just slide into the cans on the header side.

    Unit Garage Exhaust

    Yes, they are higher than the walzworks, at least from what I can tell in the fotos. They flare out a little but you can really adjust what angle they’re at - flared out, up, or down, just by where you put them on the connector pipe. I’ll get a couple photos of that probably tomorrow. I haven’t...

    Unit Garage Exhaust

    There is not a significant difference in the upper and lower bends in the unit garage pipe and my stock pipes, the difference is the short straight pipe in between that gives it a more square appearance.

    Question What boots work well with the R18?

    I don’t have the shin-banging problem (shorter legs?) but for easier shifting and braking I got the Wunderlich longer levers, they helped a lot.

    Information Brake light wiring

    I’m trying to install a ST2 brake light module. (It flashes the brake light if you slow by engine braking or downshift and don’t use the brakes). The instructions say to tap into the grey/red, grey/black, and brown wires. My rear lights have blue, brown, yellow, grey wires. (Grey and brown goes...
