Geometry-wise, the "raised-motor" TY250 I did is very similar to the Yamaha-framed 250 Majesty. It feels nothing like the Godden frame Majesty 250 to ride. The modified Yamaha frame bike feels just as short in the wheelbase as a standard TY250, but of course has better ground clearance and a slightly softer rear end. The Godden majesty carries more weight on the front end and feels longer, more stable and softer again in the rear end. Steering is beautiful on both.
The modified Yamaha frame is easier to do trick riding on than the Godden frame bike. Both are very enjoyable overall

Guy, I didn't ride my own bike much after I'd converted it.Only a few quick rides around my parents land on my practice sections.It felt pretty much as David described his modded bike.I had already done a deal to convert it to Majesty spec and then swop it for an oil in frame BSA with a 250 C15 motor.
So my original idea of ending up with a standard ty250 and a Majesty side by side to compare never happened.I have since built up another standard ty from my collection of junk,and it might get converted. The picture shows my converted one with no paint done,I think it looks good with the unpainted tank and silver frame,so if I do convert the one I have now I'll get the frame done in silver and make an alloy side panel for it.

I saw that picture on another forum, and if I remember, made a comment about the petrol tank ( soooo... nice, but sooo... expensive). I remember a comment I made on my impression of the modified frame ( mine ) compared side by side with an original frame. It feel confortable with the footrest lowered and a little back and a lot smoother ( same shock from original ) on rough terrain. I maybe wrong but my impression is the fork angle feel a bit steeper ( maybe 1/4 or 1/2 degree ) either with the original or the modified fork ( gold valve ). The rear end is smoother and have better traction on rough ground . But that's what I feel, so don't put your retirement on that. More experience rider's opinion is needed here.

Hi Guy,

Thanks for the info. As this is the first ty I have restored I didnt notice the missing frame part. Any ideas why someone would do this? All I can think of is the motor may have been raised to get more clearance? The frame seems to be straight all round but Id imagine that member would provide a fair bit of bracing.

As for the rear shocks, I can see what you are saying now that i have had a look at some other frames. I will get some measurements of the shocks and down tubes at the front where the motor and bash plate bolt on to compare to other original frames.

Im a bit annoyed to find that the frame has been hacked but I will just continue to restore as i was. It just means I will have to be more particular when selecting my next project.

I havnt made any progress on the motor yet but I think I will just clean it up as best I can myself. I decided to just paint the wheels the same colour as the frame which doesnt look too bad.

Thanks all for the info and I will post some more progress photos soon!

I have more questions than objections. You might find in the end that those modifications are a + and I would be the last one be surprise to read that you really enjoy your new toy.
