If you are willing to travel a bit to pick up your bike and ride back, make calls to Impian X at smaller town. They usually have ex-stock.

I called couple weeks back asking for a friend and black was in stock.

That's me.

I was planning to go this route before ADV350 came.
The mod is simple and original 350 engine parts go in.

Less than RM4k.

This was started by one bengkel in JB, but nowadays many bengkel offering this as it's no longer a secret recipe.
Honda 330 engine ori header parts from Thailand.

This should be the JB bengkel start started it--> https://www.facebook.com/share/p/JsAxQr4fFQJ1Gxch/

Just search "forza up spec 250 350" in facebook.

No need to depend on the mod shop for rest of your life.

Can just send back to Impian for servicing.

Nice comments.

The youtube review was a nice one. Key point is you got what you paid for. Reviewer stop short of directly commenting about reliability but enough hint from him.

Me bike noobs so only experienced Vario 150 (rented), Vario 160 (cousin's), ADV150 (first bike), ADV160 (second bike) and now ADV350.

Between the bikes you are considering and purpose of daily use through route with heavy traffic a.k.a. ability to ciluk.

Vario at 100kg can ciluk like kapzai.

ADV150/160 at 120kg, with a little getting use, can follow and ciluk like kapzai.

ADV350 at 185kg, after 2 weeks riding in town, not as nimble as kapzai but surprisingly quite easy too. Ran few trips Jalan Kucing from Batu Cave round about to Loke Yew / Pudu during peak hour. Could ciluk through as good as my ADV160, slower when switching lane going in front of cars to another lane.

Forza NSS and XMax has the same "narrow" body design like ADV350 so they can also ciluk well.

Zontes 350e at 210kg, on the other hand, it feels fat and wide when I sat on it in the showroom. The youtube video shared also mentioned this and compared against Forza and Xmax. While it's doable to ciluk, it will take a while to get use to.

For your thought of long trips, underseat storage in this category (250-350) is the best. Only slight difference between all the models you mentioned.

Oh, forgot to mention.

I had buyer remorse when I was picking up my ADV350 and saw the much much elegant Forza NSS beside, with sexy large windscreen, car like rear view mirror, sexy body lines like adik air buah... fuyoh.. never thought XMax look can get outdated immediately in my mind after looking at this sexy NSS.

Ok ok.. each to their own, one man's meat is another's poison... excuse me.. where's the tissue box..
