16 Year Old KTM 450 EXC (RFS) Engine Test Ride

Just got my hands on a 2007 KTM 450 EXC, last year of the RFS (Racing Four Stroke) Engine. Let's go for a test ride on some local forest trails!
2007 : This was the first year that the 450 EXC was offered in full factory 50-state street legal trim. The conversion of the previously available model required changes in gearing, exhaust, DOT approved tires and lights and the addition of turn signals, and a horn. Other than these changes the bike was virtually the same as the previously off-road only bike. The US off-road only version of the EXC was replaced by the XC (Close-ratio transmission) and XC-W (wide-ratio transmission) models. 2007 was also the last year of the RFS motor. The RFS is very torquey and is known to have very good reliability. In some cases, the fully stock engines last for more than 45k miles. The RFS bike is known to be a good dual sport and super motard bike. The wide ratio 6-speed transmission will run all day long on the highway. Due to their dual-sport ability, there are larger aftermarket fuel tanks available.

The short shifting during that street pull made me giggle lol

Thankyou for sharing your new toy with us.
My 1st bike is the same model and instead of guying a new one when the motor was due for a rebuild(over 400hrs) I've torn it down and gone for a full rebuild, it's nearly completed now and can't wait to ride it again.
Fantastic bikes these rfs motors are.
Stay safe and enjoy!

i still have my 2005 450exc since 2011. no issue at all same piston and almost everything.

Have a 2002 KTM 520sx with an Acrapovic titanium exhaust and it is pure madness. It pulls like crazy and wheelies in every gear. Only problem for me is the very tall 1st gear which makes trail riding more challenging. The engine is as far as I know all original since I got it in 2005 and still runs great.
The RFS engine is truly great with its torque, reliability and its deep sound

Have an 04' 450SX, what a beast !

I have a 2004 450 EXC and it’s a really great bike and very reliable. I have since added tusk panniers, newer style headlight and front fender to get a brighter down the road view. Also have an acerbis 6 gallon fuel tank for it that I found on vacation in Florida for a $100. Have the trail tech Voyager Pro on it instead of the stock cluster. Tall seat, heaviest springs for my weight and the adventure pegs from Fastway which are like floorboards and have them in the low position. Also running the Tusk DSport Adventure tires and it’s great on and off road. I don’t plan on ever selling it.

...and good to see the gates are open!

[cmonkey]

Yup. You’ll get more comfortable with the power and the fact that it “ lighter”. Still not a 300xcw but you’ll be able to clutch the front end over those wash out and ride over them standing instead of having to plow through them like a big bike would.

2007 was the best and last year of the RFS 👌

[dREaDneck_Moto]

Nice, dude, glad you picked up a play bike. See you out there.

[dennismacwilliams]

What A cool bike nice pick...
In just found your channel and I'm glad I did...
Thank you

[bndocker]

Alright! I've been waiting to see this thing in action!

[Hebhansen]

Hey Chief. Looks really fun! I’m new to KTM, so I wonder is RFC the same as R?

[theadventurousrider]

ok that was quite brave running up those rocks like that. I would have busted my butt doing that. Like the offroad jump there at the end. Wonder what a car would have done if they were behind you. LOL

[Sinaassnipper]

Nice video, i had the same year. Great bike, never had any trouble with it

[cmbscx]

Loved my 07' 525EXC and love my 07' 450EXC. Check your counter shaft spline for wear, change the CS sprocket, put a Dirt tricks washer a JD jetting kit and have fun trying to wear out that RFS. AKA Orange DRZ or a XR in Orange plastics.

[mikej]

nice, ...i have the same combo, 15' 1190r & 05' 450exc. i wouldn't pass it on of you want newer... I'd keep it as a "buddy bike", just rebuilt top on mine last year, new piston kit and sainless valves, carb rebuild. Parts for the major stuff is out there and the rest is generic. I'm in Broomfield so maybe I'll see you out there 🤙

[nickandmotorcycletime]

How has this bike been reliability wise? Im looking at one. Do I need to go crazy on valve checks or is it a myth. I dont mind frequent oil changes. Thanks!

[MarioDuranoficial]

Guys, I'm new to these bikes, can I use this bike as a dirt bike, kinda like for trails and woods, or what model do I choose, help please. I been on street bikes for over 15 years.
