OTHG MX LACR South National

[powr-photo-editor id=ec1b7872_1507691630]

Last weekend was the OTHG MX LACR South National. Racers from all over California and surrounding areas came out to battle it out for two days of racing. All the racers rode at least 2 motos per day and a lowest overall score for the weekend would decide the overall winners. With summer coming to an end there were cooler temps in the morning and evenings.  Arriving the Friday to a fully packed track with many racers camping out. The LACR track crew did a great job to prepare the track. The course is about 1.5 miles long and nets around 2 minute lap times.

The pits filled up fast on Friday.

The N2Dirt riders showed excellent speed. With onsite suspension support the riders were able to get bikes checked out on dialed in before the races. The track got rough super fast with a lot of racers trying to set the pace to win. Our crew was busy setting sag and consulting riders on line selections and  racing strategy.

LIT Pro with onsite demos.

We were able to connect with the LITPro team to analyze on track data to improve lap times. Litpro is high definition GPS over-laid  on an over head photo of the most current track design. The data is very helpful to understand where you can make up time on the track. The guys were able to explain the applications power in racing. Adding sensors to test suspension speed and travel is the next step in the game for us. Real time data of what the suspension is doing to aid in tuning. This will help eliminate some of the guess work of getting good settings. Along with these options the Litpro shows what sort of G forces the rider is experiencing. There is a direct correlation of G force and lap times. We look forward to working with Litpro in the future.

Several N2dirt riders won throughout the weekend. Here’s a list of the winners:

  • Scott Sligar 58 Expert
  • Kevin Barda 52 Master
  • George Andrews 52 Intermediate
  • Sean Collier 30 Master
  • Brian Bolding 38 Master

2015.5+ KTM/Husqvarna linkage Specifications

Designed in collaboration with Luxon MX, N2dirt Suspension has created a high performance linkage to address the shortcomings of the 2015.5+ KTM/Husqvarna rear suspension.

These improvements include improved handling, wheel travel, and bottoming control.

The image below has wheel rate graphs vs stock positions to illustrate how our linkage can accomplish this by changing the rear suspension movement. The addition of this linkage is the first modification before any spring change or shim setting as they will need to be matched.

A48R with Shock Huck Valve Expert setup

We now have a dozens of rides on the latest version of the MX-Tech shock huck valve with AER fork on our 2016 KTM450SXF.

This mod is intended on running it in conjunction with the PC complete linkage, TANK, Triple Adjuster, and 5.2kg/mm spring. 195lbs Vet expert moto/gp settings.

First impression is huge improvement of bottoming resistance over revalved shock. I used to have a good amount of rub marks on the fender after a long moto and now I am just noticing the dirt is just getting rubbed off and no tire mark. The presents of the bottoming system is there and you can feel it but as long as your compression clicker isn’t backed out to far you don’t feel it come on too much when it’s low in the stroke.

Watching the action of the rear end of the bike looks so much different than a stock setup bike. Much more controlled motion and planted feel. Traction is greatly improved as you don’t need a really stiff low speed compression stack to compensate for bottoming resistance.

With the triple adjuster you can really dial in the low speed rebound to keep the back tire biting when unloaded on entry of a low speed roller into a turn.

Seat bounce any jump face out of a turn with confidence that you won’t blow through the entire stroke instantly.

The balance of the bike has improved to match the bottoming resistance of the AER Fork. While we are happy with the results so far we aren’t done tuning yet and will continue with races as weather is permiting. Stay tuned!

WP AER Midvalve Leaf spring mid valve and plastic piston replacement

2017 KTM and Husky models fitted with the AER Fork contain a solid clamp mid valve or a wave washer mid valve.  Along with having tuning constraints they are prone to failure and WP updated the new models to a sintered piston. We have a fix the Aer leaf spring with mid valve piston will also give the fork a much better feel. It is highly tuneable and durable.
