This is a hybrid build. TTR230 engine in a YZ250F frame.
What would an ultimate TTR230 build look like? I looked up an AJP 230 and whoa.... what a bike, and still a hefty price.
One of my recent project bikes was a 2011 TTR230. It was low, so easy to mount, had decent power, 6 speed gearbox, disc front and drum rear brake. I took it on a local single track run, and it did just fine, but was lacking in brakes, and suspension. So my "wheels started turning". Maybe I could do a version of the AJP, only full on Yamaha all the way thru. All disc brakes, lower seat, simple air cooled. So install a 230 in a YZ250F frame. And all of a sudden, there was a 250F frame for sale.... and then a 230 engine. Oh man, there it is! So I snapped on both, and started the build back in October, 2019.
Only way dreams become reality is to bring out the Sawzall and the MIG. Here goes...... and ......... its a bike! Date is Jan 2, 2020. I've ridden it up and down the street, and still have some finish and detail work before a trail ride, but it runs, and proof of concept is definitely there. Its in Thumpertalk TTR section as: TTR230 Ultimate Build. I'll post more when I get a ride in.
