Nice job.
Looks great.
I agree, seats sold around are too humpy and droopy backwards. Already too common as well. Every Honda modified has them.
Yours looks better, more original that the carbon copy others. Plus I agree, no need to cut frame.
If needed, you can have the original seat or modify the original seat as well, to have a sleeker look, yet retaining its length, in case you want to have a passenger. Nothing worse than having a girl interested in ridding along with you, and having to say no. No way.
You can switch as needed. A bike which frame got trimmed, is fine, but is limited for ever.
