Am I too fat

I really want to buy a R3 this July. I know I might want a bigger bike later but I want to learn on a R3 a d later give it to my wife.

I'm 5'11 and 275 pounds with normal clothes on. I'll never have a passenger.. but question I have is will a R3 even carry my and still move decently and not bottom out? I know I need to lose weight and am working on it. A year ago I was 330 pounds. I know I was almost too heavy then . Please let me know.

The suspensions will be a bit soft for you for sure, but that's easy to change. Springs are meant to be changed on bikes to suit your weight. Manufacturers usually set the suspensions out of the factory for someone that's around 150-180 lbs depending on the brand and model, so probably a lot of us are too heavy for it. Change your springs and you'll be fine.

Oh and good job on the weight loss and keep up the work! I've been struggling with it for years! I was at 240 at my worst, and now I'm around 215. Hoping to get to 200 but I've sort of hit a plateau :/

Congrats on the weight loss. There are some heavier riders or there on an R3. That said, haven't heard of anyone in your range with the exception of maybe one other guy on this forum. Can't remember his name but it had "wolf" in it so if you can find his posts then that should give some insight. If you have the preload set at max on the shock, the rear may work out. The front springs are def going to need swapping out to a heavier one. Another bike to consider for your weight might be the ninja 650. A used one can be had for the same price as a brand new R3, and some used 2012+ 650's are in the same range as the used R3's. That bike has really heavy fork springs, 1.1kg/mm if I recall correctly. That bike is a pretty good beginner/commuter bike as well so even if you pass it down to he wife, it should/could be beginner-friendly. Everyone is different, I moved from a 1999 ex500 to a 650 after 3000 miles. I'm 144 lbs on a good day and the bike never felt overwhelming to me.

I looked online to see what kind of springs they had. Was not very successful in finding really anything.

If this is your first bike you'll be fine on stock springs. The shock is preload adjustable. Not trying to say proper suspension isn't important, it is when you want it to be. Once you move past riding around your neighborhood or church parking lot, then YOU can decide if you need it or not. You'll probably find the suspension is just fine. Be careful out there and have fun. It's a good bike.

Edit: also want to add, respringing stock shock is a waste of time. It pogo sticks already as is under hard use. If you start upgrading suspension, do it right, and it's not cheap.

I would disagree with that. i am not sure what the exact spring weight is up front, but for a ~144 lbs rider the front definitely feels really soft. I can't imagine what it would be like for someone almost twice my weight would feel riding it.

Agreed. If it's anything like the ninja 300s, it's too soft. I weigh considerably less than him and I bottom out the front end on the ninja 300s all the time (I ride a lot of them because that's what we have at the place where I teach MSF classes). Any hard braking combined with going over a little bump and I bottom out. I can only imagine weighing an extra 50 lbs would be a guarantee.

True enough, it's soft. But the guy's just starting out. Let him get a feel for it first, he might feel fine the way it is. We all ride differently. Changing springs only is still a waste for the benefit. Changing fork springs? Might as well drop some emulators in there too if you're going through the trouble. A stronger shock spring would definitely blow through any damping ability it has. OP also stated he just wanted to learn on it and then pass it on to his girl.

Morgan, if you're willing to spend any money at all, springs and emulators in the forks, replace rear shock with a single adjustable unit. If you do springs only, you won't be happy for the time and money spent.
