PhilDawson8270 Posted December 2, 2010 Share Posted December 2, 2010 No reason for me to echo what all others have said about it being the better rider, that is obviously true. Out of curiosity here are some figures. YBR 10:1 Compression YZF 11.2:1 Compression YBR 7.5kW @ 7800 YZF 11kW @ 9000 YBR 9.6NM @ 6000 YZF 12.2NM @ 8000 Can see here the YZF is slightly more powerful, but will need to be worked harder to keep the revs higher for the performance. YBR 5speed YZF 6speed This will help with keeping it revvy, as gearing will be short, but may be a hassle town riding. Caster and Trail both are shorter on the YZF giving quicker steering, and wider tyres giving it higher lean angles, and is likely to also have larger ground clearance for faster corner speeds. YBR is 125kg YZF is 138kg So you already have 13kg weight advantage. All being equal the YZF-125R will probably be slightly quicker, but biggest difference will be the handling, unfortunately it is down to the skill of the rider to extract the most from a machines handling.
