i brought a Suzuki Raider 115 FI... last June 2014... im impress to its power and mobility..i can compete to 125 and 135 motorcycles... with this powerful 115 electronic fuel injection... i use 93+ octain rating .unleaded fuel for optimum power efficiency because i tried 91, but the result is hard starting specially on rainy season(cold engine) hard to warm-up cuz of low temperature generating FI engine.. my only problem is its low idle RPM..sometimes when heavy trafic my engine will go off.. and ill start it again.. the only thing im impress with this new J115-FI is its design and engine performance.. so far..no regret..with proper brake-in....im enjoying 110km/h max speed in highway..
