If u want speed and looks, buy a high cc motorcycle. Mao na akong sayop sauna magpalit ug barato ug hinay nga motor unya pakusgon. In the end kuwang gihapon.
To tell u honestly, when u finally own a high displacement bike magkatawa ka sa imong gipangbuhat sauna sa imong underbones
My ninja 650 is super quite and yet can easily surpass any customized underbone with no more additional tunes. Thats engine-wise and handling wise. Sa maintenance wise gamay ra jud kaau ug difference and yet performance wise ikaw ang sukdon. No more vibrations, no more puga2 and no more hassle. Just ride ur bike and feel the pressure.
Ride safe.
Open mufflers are just distractions and mostly wrong perceptions esp on low cc bikes. Plus 10km/hr and tops? Haha waste of time and money.
