Default Re: 2-stroke vs 4-stroke

bottom line, it's personal preference. what kind of performance do you want? what is your budget? what skills do you have?
what bike engine are thinking thats that powerful and small? im looking into new engine options
Are you callin' me crazy! just cuz i got a hotel in my foot doesn't make me a boogali moogali moogali
