2017 Husqvarna TC 85 17/14 Dirt Rider Project Bike

How to Make a Fast Mini Faster

A young racer could find themselves on the gate against one or more of the nation's most promising factory recruits on their finely tuned factory machines. Luckily for these mini privateers, they have access to the same equipment that we put on this project 2017 TC 85 for young racer Jack Carrigg.

 

Jack rode the 2017 TC 85 in stock form first to get a good feel of what we had and where we wanted to go with it. The feel of the cockpit was well liked immediately. The bike felt narrow between the legs, its seat seemed long and fairly flat, and the controls were well positioned and with that great hydraulic clutch that's easy to pull. The TC 85 is a bit longer and taller feeling than most of the Japanese brands, and it did take a few laps to begin trusting the lean in through inside ruts at speed...

Air-To-Spring Conversion Kit

WP AER 48 Air Fork and Showa TAC Air Fork Conversion Cartridge

Spring Conversion Kit

 

For riders that prefer a more traditional spring system over air forks, Pro Circuit is now offering a simple spring hybrid conversion cartridge kit that can be easily dropped into your WP AER 48 Air Fork or Showa TAC Air Fork*. The fork cap on this conversion kit comes with an air valve that can be used to add just a touch of air to make the fork a little more progressive through the stroke for the faster, more aggressive riders, or even to compensate for special conditions, such as a mud race. It can also be run at zero pressure for the riders that don't want to mess with adding air in their forks. The kit also offers easy spring preload adjustment without taking the fork all the way apart, letting the fork ride a little higher or lower when needed. This hybrid fork spring system is 100% made in the USA and is available for the following applications:

 

2015-2017 Honda CRF250R
2015-2017 Kawasaki KX450F
2016 1/2-2017 KTM SX 125, 250/350/450 SX-F
