KTM 690 TRACK BIKE - Just like a Kramer but 1/2 the price.

[youngie]

This bike started out as a 2014 KTM 690 Duke that was bought new in 2016 and built into a race bike. It now displaces 732cc, makes 72HP at 5400ft (so well over 80hp at Sea Level) and weighs 278lbs with all fluids and a partial tank of fuel. The engine was fully rebuilt before the 2024 season. In 2024 the bike finished 2nd overall in the MRA (Colorado) Supertwins GTU and Lightweight XX championships, 3rd in Lightweight GP and won Formula Colorado. In 2023 it finished 3rd in Supertwins GTU, 2nd in Lightweight Endurance, 4th in Lightweight GP and won formula Colorado. This is all just to say the bike is competitive. If you are better on the brakes than me, you could do even better. This should be an excellent AHRMA SOS bike. Back-cut intake valves and head porting by Race Tech, cam and over bore kit are from Poskit Racing, Power Commander V with Auto Tune. Custom ram air system. Exhaust is a semi-custom full system from Werkes USA. Dyno tuning by Brian at Speedin’ Motorsports. It does not require race fuel, can run 90+ octane pump gas. The forks have Andriani springs & cartridges. Shock is a Penske double adjustable model 8983, lengthened for better swingarm angle. Steering damper is a straight-through Tobey. ABS system has been removed, front brake has a 15mm Brembo RCS radial master cylinder, SS line to the stock caliper running Braking Tech ventilated pistons and Vesra pads.All street-related and otherwise unnecessary wiring has been stripped out of the harness which has also been re-configured for better valve cover access. Lithium battery.Upper and lower fairing are from Hot Bodies, tail section is Airtech, airbox is custom. Woodcraft spools, brake protector, bar-end and frame sliders. Clip-ons and foot controls are Woodcraft. Fuel is carried under the seat in an aluminum fuel cel, subframe is custom. Carbon front fender. I will supply a complete list of parts and sources with the bike to simplify repair and maintenance. This bike is 100% READY TO RACE, needs nothing but a fresh set of tires and your race numbers! It comes with an MSO.

The wheels are stock KTM. They are respectably light, no reason to change them. (I mean, mag wheels are awesome, but very expensive, so there were always other things that needed doing more.)

The colors and graphics you see in the action shots were a full graphic wrap. Since it had my name, race numbers and sponsors on it, I stripped that off, wet-sanded the body and gave it a coat of gray primer, also wet-sanded. It is ready for whatever you want to do with it. You can see that in the two still shots of the bike in the for-sale post, I'll attach one here.

The bike is set up for a rider weight of 200lbs; that's with all gear on. I'm between 170 & 175 w/o gear.

Spares; as I write this I'm remembering that when I put the Andriani cartridges in I started with a 7.8kg spring in one leg and an 8.3kg in the other to get the 8kg spring rate I thought I wanted; that turned out to be just a little stiff, so I changed to a pair of 7.8 springs. I'll send the spare 8.3 spring along in case you want to stiffen it up a little.

The rear shock is a Penske "Double Adjustable", model 8983, and the spring they supplied with it is marked 0700.225.0600. It gave correct sag numbers so I never thought about it again. If you think you are going to need to re-spring it, I'm sure you could give Penske that info, and how much heavier or lighter the rider is, and order up a spring ahead of time.

Hit me up if you have any questions. I am out of the country but by son can sort out viewing, purchase etc. Asking $7500 bike is currently in Chico, CA but it maybe able to be dropped off in the Bay Area or viewed in Sacramento with some planning.

Hi John. This is a really nice build. What sort of engine maintenance is required? Are we talking a full engine refresh every season? I am most likely not racing, but I am looking for a turn key track bike. I like the idea of a lightweight fun bike, but don't want to sign up for complicated and frequent maintenance. Like if I did 5 track days in a season, what does my maintenance schedule look like? Thanks!

I guess it depends what kind of riding you are doing and your experience level. 5 track days a season, is that a 'C' group track day or an 'A' group track day? If you're just a 'C' group rider I would perhaps check the valves every couple of years if you're an 'A' group rider I would check them end of every season. I would change the oil in it 2-3 times a season if you were doing 5 track days regardless of your experience level. The faster you go, the more it costs. I used to race a TZ250 in AFM so I know that all too well ;-) Funny your screen name is StealthSwede, do you know Reine Perrson at Swedetech?

Thanks. I'm a solid A group rider. I raced SV650's in AFM for several years (2:00 at Thunderhill, 1:49 at Sonoma) although I'm not as fast anymore (I got old!). I've ridden the track for 25 years +.

I would always change the oil after a track outing, but I was mainly worried about having to take the engine apart. Doing some reading on checking the valves on the LC4. You mentioned you had moved some of the wiring harness to more easily get to the valves?

 

[StealthSwede]

Oh and yeah, I'm Swedish, but I don't know Reine. My claim to Swedish fame is that my dad is friends with Tommy Öhlins who founded the suspension company. He used to build my dad's endurance race car suspension, and he's also sent me some one-off shocks for older race bikes of mine.

Valves aren't too big of a deal on the LC4. Rocky Mountain ATV did a detailed "how-to" video a few years ago. I'm an absolute hack and I can do it with the help of that video. They also do a video on top end replacement.

2:00 is a solid time at TH and good going. The older we get the faster we were ;-) My best track was Buttonwillow where I had the least seat time. I was running 56's but this was 20 years ago, things have got a lot better, track, tyres etc. I bought this bike "as is" and have done nothing to it. The guy I bought it off was absolutely fastidious though.

Reine used to help build my TZ250 motors and we were getting 83hp out of the 4TW models. He now builds and races shifter kart motors getting 30hp out of a CR80 motor, I have one in a motorcycle.

You ought to be fine then but of course I can't guarantee anything as nobody really can, parts wear, things break. I remember one AFAM weekend I broke two cranks on my TZ's - swapped it out at the track and still raced Sunday though. Madness when I look back
