Will do! I weighed the bike with a full tank of gas and it was 338lbs. Looking at the stock headlight vs the one thats on there I would assume you lose a couple pounds but the bike didn't come with the stock one so I can't say for certain. Its basically plastic and two bulbs so it can't weigh very much. With a 15/41 combo on the bike I can barely keep the front wheel down as it is. It'll do power wheelies in 3rd gear with no problem. Need to get a lighter tank on it to lose some more weight off the front.. 4th gear power wheelies? Yes please!
