So a KTM690 Enduro states it has a hp of 66 at the crank
KTM 690 Enduro*R 2014 - Highlights
but at the rear wheel it is 46.3 hp?
"This is one potent single. KTM
claims 63 crank hp at 7500 rpm. Our dyno testing yielded 46.3
rear-wheel hp @ 7250 rpm and 35.65 lb.-ft. of torque @ 6500
KTM 690 Enduro SMC Factory Pro 800 869-0497
So my DRZ400 its getting its wide ratio gearbox fitted shortly however it will also be close to 50hp at the rear wheel which will not effect its realiblity at all if done correctly as many people are getiing 40,000+ miles with this kit on

39mm "MX" FCR Carburetor (Tuned & Jetted)
94mm/440cc Big Bore Kit
Hot Cams Camshaft Set
I was going the fit a +4mm stroker crank to make it to around 470 as i am spillting the case's anyway for the wide ratio gears however more work will then be needed to the head and also will need new stronger valves than the standard stock valves, to much into this build and also head gaskets blow so with the above mods it will run fine with no issues and i decided to go with another type of 94mm bore kit that has wider water jackets for better cooling. the drz400e has a slant body FCR carb fitted however there are know issues with some case of the vacuum plate breaking up and getting crunched up in the barrel smashing valves ect ect so i am going with the better 39mm "MX" FCR Carburetor (Tuned & Jetted)
The slant body carbs were stopped from being fitted to big production singles due to the vacuum plate being at an angle and all the intake suction presure being on the bottom of the plate, causing them to crack and fail in the long run,
Along time ago there was a rumored ''BIG'' dispute between ktm and keihin as there early 620 and 660 factory bikes were breaking the slides and causing valves piston and bore to end up in very very bad ways which wasnt cheap i believe even yam had a few problem with the early yzf400/wr400f with the same slide issue as why the only known bike to be produced with a slant body fcr after that period was the drz400E
