Compare GXV140 and GXV 160 you have difference 5HP and 5.5 HP and that was the spec more than 10 years ago .Now they dont made GXV 140 any more and look at the spec of GXV 160 on Honda now you will find out it have only 4.3 HP that because they try to reduce pollution ,lately HRC216 not for sale in CA anymore and the spec go back to 5.5 HP at 3600 rpm . To be honest I'm using HR215 and HR 195 for long time at close to 4000 rpm with out any problem
