Help!!!

I have no experience with either and after doing some searching it appears some readings suggest the Suzuki is a bit faster, and "IF" that is true, I would not be surprised as Honda tends to lean more towards governing speed on various units they produce. Personally, I like Honda and believe it would be a great unit for you, tons of fun, and highly reliable for many years to come, so I don't see a downside. However, if you are planning on riding and trying to outrun everyone out there on the MX track, then you might consider looking across all the units including and not limited to Yamaha as well.
