Öh­lins TTX Flow £988

Cut­ting-edge mo­tocross shock could be shape of things to come

Motorcycle News (UK) - - Garage -

Swedish sus­pen­sion gi­ants Öh­lins are cel­e­brat­ing their 40th an­niver­sary with a new shock tech­nol­ogy they say is a clear step for­ward over ex­ist­ing sus­pen­sion units.

The TTX Flow is a mo­tocross shock that’s been de­signed to in­crease sta­bil­ity in the tough en­vi­ron­ments of off-road rac­ing. But Öh­lins say the tech­nol­ogy in­side the new shock could be ex­plored for po­ten­tial ben­e­fits in other forms of mo­tor­cy­cling.

The new unit uses the firm’s TTX twin-tube set-up, which al­lows bet­ter reg­u­la­tion of forces caused by the com­pres­sion or re­bound stroke. But the new de­vel­op­ment is a sys­tem that di­rects at­ten­tion to the in­ter­nal cham­ber most in need of prepa­ra­tion for the next di­rec­tion change.

Öh­lins say the key to op­ti­mum sus­pen­sion per­for­mance is al­low­ing a unit to set­tle as quickly as pos­si­ble af­ter a move­ment. The aim is to quickly get back to a shock’s static pres­sure value, which is the same as when the bike is sat still.

The com­pany say their new tech­nol­ogy does this quicker than ever, al­low­ing the TTX Flow to set­tle in less than 100th of a sec­ond af­ter a hit. It has taken two years to de­velop and test and it has al­ready seen ac­tion in mo­tocross Grands Prix.

Öh­lins are be­ing care­ful not to give away too much about how their sys­tem works, but it es­sen­tially re­lies on a de­vice in­side the shock that reg­u­lates whether to re­set on the re­bound or com­pres­sion side, depend­ing on the ex­ter­nal forces it has just been sub­jected to.

"WE have tested it with our own test rid­ers and also some 'neu­tral’ test rid­ers, and one of the neu­tral rid­ers took it and used it in a Grand Prix," Öh­lins’ off-road prod­uct spe­cial­ist Christo­pher Nils­son told MCN.

Nils­son ex­plained that, be­cause the TTX Flow is able to cope with a wider range of shock travel speeds, the new tech­nol­ogy will ben­e­fit rid­ers of all lev­els of mo­tocross. Where an ex­ist­ing shock may need to be set up to work for a GP rider, mak­ing it less use­ful to the amateur, the new tech­nol­ogy will be bet­ter able to cope with both rid­ing styles.

Öh­lins have also worked on the user-friend­li­ness of the new shock with de­vel­op­ments that will cer­tainly ap­peal to the road rider. They have al­tered the preload ad­just­ment to make it sim­pler to use and the damp­ing ad­justers have in­di­ca­tors to eas­ily re­veal the cur­rent set­tings.

The new shock is avail­able for most main adult mo­tocross and en­duro bikes and there are a wide range of springs avail­able in dif­fer­ing weights to suit the rider. The shock it­self costs £910 and the springs are bought sep­a­rately for £78.
