They need a little cleanup but are runners. The red DT actually has a wrangler jean jacket made into a cover with a serious fade.

And if you needed any more reason to get psyched on the old enduros check out these guys instagram accounts. Tons of great old photos.

I spy Vic Eastwood and Hakan Andersson. #motocrosshistory #motocross #worldmotocross #realmx#natualterrain#70’smoto

All were 69-71 era, piston port motors, before Yamaha really knew what dirt bikes would become. And all were relatively about the same dimensions, just different weight.

Lately I’ve been regretting buying my 71 CT1 since it’s lacking the newer technology compared to the late 70’s. I really wish I had bought a 78-82 dt175 instead; way better suspension and faster.

Regardless… I’ve been looking at ways to make mine better from a performance and suspension standpoint and after finding all these cool images, it gives me some solid inspiration. Some of these bikes below are badass! This is what I’m thinking:
– already have pod filter and jetted carb
– GYT expansion chamber exhaust
– aluminum rims. small front hub. no front brake
– plastic front and rear fender
– smaller front gear. bigger rear gear
– front end from a YZ or MX
– maybe take all my lights off and put a number plate on it

Yamaha had a power kit from the factory called “GYT”. (Genuine Yamaha Tuning)

You could walk into a Yamaha dealer in 1970 and get a new piston kit / carb / gear / exhaust (all yamaha parts) to make it go faster. I’m trying to find some of this stuff on eBay but its super rare.

FYI – the hot exhausts were:
– GYT
– hooker
– DG performance
– torque engineering
– bassani
– moto tech
