As SneakyDingo says:
When adding or modifying your motorcycle check for the whole setup as a complete set.
Several of the skid plates do not fit add on engine guards and some engine guards require very extensive work to install. Many of the exhausts require extensive work.
Procurement and Installation of added crash guards
I was concerned about safety and protecting me and the bike after falling.
I wanted to keep the original Honda skid plate.
I made sure the Diablo Engine guard V2 fit properly before purchasing.
I contacted K-SPEED in Bangkok to ensure that both the motorcycle's balance and weight was not affected. It only added some grams. The V2 model has 2 small added side 3 hole steel plates that were added after crash testing the Honda Trail 125. The bikes center of gravity is lowered slightly.
The Diablo Engine guard is sold by K-SPEED as

I chose BEEZDEELZ over K-SPEED and Bangkok eBay resellers using a credit card vs PAYPAL.
