Hi there and greetings from Thailand - Here's my bike with details of the mods done: EJK Fuel controller FMF Mega Bomb Header FMF Q4 Silencer 13 tooth engine sprocket. Modified air box Power is up by over 30% - from the lights and mid range - the acceleration is blistering. Standard thin and rock hard seat was replaced with a wider, memory foam "seat Concepts" Seat, imported from the USA - (http://www.seatconcepts.com/products…) Carbon cover for Mega Bomb header (to save burning your leg...lol..) Zeta "Shorty" adjustable brake levers Zeta front sprocket / chain adjusters and gear lever. Rear carrier Acerbis "Tri Fit" Hand Guards Renthal cross bar pad. Oh, and the decal kit, custom made by a place in Bangkok with the "55" on it to remind me of my 55th birthday on the day the decals were delivered...lol...... I've found the "M" model to be pretty much perfect for the bumpy and pot hole infested roads round here......and because of it's dirt bike DNA, its great on dirt tracks, as long as they are dry....
