Redline Rebuild: Honda Trail 70 restoration explained - Hagerty Media
The Honda CT70 is looking beautiful after its Redline Rebuild treatment and, of course, it’s running like a top. Davin is not one to keep secrets about the work that’s been done and what challenges arose along the way. There were plenty of updates along the way, but sometimes the best time to talk particulars is when looking at it reflectively. So Davin and lead videographer Ben sat down to talk through the nuts and bolts of this big little project.
First, Davin explains why he chose a Trail 70. “We’d been getting messages about doing something other than an engine for awhile, and motorcycles always rose to the top of the conversation. Between my personal experience with the Trail 70 and its nearly legendary status with enthusiasts, it was the perfect choice.” Of course, when it came time to pick up a restoration candidate, Davin fell back on an old maxim: Purchase the best example you can find to restore. In this case it meant a running and riding bike.
“That machine was pretty tired though. Complete, but tired.” That often makes things a lot easier for a restoration. Documenting how parts fit together during disassembly is a lot easier when they’re all there. Also it can make better financial sense to buy something with parts that can be restored rather than swiping the credit card for each missing piece. Davin guesstimates there are about as many parts into the entire Trail 70 than a single V-8 engine, which means this project might look fairly simple, but it can also be deceptively complex—mainly to keep organized once it’s all apart.
In that blown apart phase it was all about cleaning and acquiring parts. Luckily, Davin had the experts at Trail Buddy on call to help find and advise on just what he needed. They also helped rebuild the front forks and sprayed the tri-stage candy paint, a paint that surprised Davin both then and now. “It really blows me away that Honda would have done such a complicated paint process on what amounts to a kids bike. These were often used and abused, and that paint makes touch ups really difficult.” No matter when he was re-spraying the entire frame.
Then it came down to assembly, which is where this man thrives. Between Davin’s trusty shop manual and the guys at Trail Buddy, the bike slipped together quite quickly. Now it’s ready for some off road adventures—right after someone puts the first scratch in that beautiful paint. Davin is still a bit squeamish, but he knows that after that first ding, all bets are off. This bike was made to have fun, and that’s what it’s going to do.

Had just started refurbishing my own CT70H that I got on my 14th bday in 1971. It’s been sitting dormant for years, and I wanted to get it going again for my grandsons. Ran into a couple questions when trying to disassemble and decided to “You Tube it”, as all the young people tell me to do nowadays, looking for a quick answer. Ran into your video, and ended up sitting there watching the whole damn thing! Didn’t really get an answer to my particular questions, but thoroughly enjoyed it!! It’s great to see people who really know their stuff, and are having a good time doing it!!
