Max as of March 3rd, 2013. The seat post is in a newly lowered, set back position. I've replaced the springer forks with mountain bike forks. I also added some very powerful lights. I now have a machine I trust. She can ride up hills I cannot pedal up with my road bike in the lowest gear.
Let's see... I also figured out the proper technique for double nutting. The exhaust and the motor mounts do NOT shake loose.
No question about it. Thing is, not everyone likes them, and they don't work for everyone. Saddles are a personal choice, but for people that fit a Brookes, cost is the least consideration, for they last ten times longer, so they are actually much cheaper by the mile.
