Well, after having Traxxion AK 20's on both of my '06 bikes, which now have new homes, I just couldn't stand not having them on the new SERGU, and I said back then that I'd never have another HD without their suspension on the front...sooooo, I made an appointment for this past Friday and made the ride over to Woodstock, GA. It's about 140 miles from my house to their shop, and I lose an hour going over, so I left B'ham about 6 AM Friday morning, and got there about 10AM...I took mostly back roads to avoid Atlanta interstate traffic. Dan wrote me up and one of their newer techs (Tony) pulled the bike up on the lift and got started about 10:30 or so. Tony took great care to protect the bike's paint, just like they did previously. They really are a class act at Traxxion...they even let me borrow the shop's tricked out Gold Wing to ride when it came time to eat lunch. Tony is great...he had the bike back together at 2:00. They have really got taking the HD forks off down to a fine art...when Don and I had ours done back in '07, it took them most of the day to get the work done...now, it's less than 4 hours, and that included a lunch break for Tony.
Once again, all I can say about the Traxxion AK 20 cartridges is WOW

Again, a night and day difference over the crap that Harley calls front suspension. The bike now has that familiar feel that I enjoyed so much on the other bikes. I said it back then, and I'll say it again...it's the best money I've ever spent on a motorcycle. It just makes the bike more pleasurable to ride, and safer to boot...the front just absorbs every little bump, and those teeth jarring sharp edged bumps in the road are simply absorbed like they aren't even there. The bike tracks 100% better, and is totally predictable in curves, even if you have to make a mid turn corrrection. The bike just responds better to every input from the rider to the bars.
Yes, there are cheaper alternatives to the Traxxion system, but there is NOTHING that can compare to their product, IMO. Two thumbs up to everyone at Traxxion...they are a class act, with the best customer service I've ever received.

Can't recommend them highly enough...if you want the best front suspension out there for a HD, get Traxxion Dynamics...you will not be dissapointed.
