Island Classic 2019

Wilderness racing attended the Island classic again this year under the Ron Angel Classic racing Umbrella. With Peter of Promecha looking after the suspension on the TZ350 he had fitted a new shock and some brand new “Pro Valves” into the front forks. These fork cartridges are made totally in house at Promecha, they give the bike a whole new feel, making the TZ 350 a pleasure to ride. After a couple of sessions on Thursday to dial in the new suspension we knew we were on the right track. With qualifying on Friday we put it on pole position with a 1:49 lap not bad for a 1979 350.

We were first race up Saturday morning and led from start to finish getting down to 48s even with lacking a bit of speed due to a head wind. Race 2 after a few more tweaks under Peter's instructions we got down to 47s also taking the win. Race 3 we maintained our pace with a 1:47:3 winning by a convincing 13 secs. Race 4 we brought it home with another string of 47s and won by over 18secs almost getting the lap record, missed it by 0.08 secs, so close, maybe next year.

In the process of having a perfect run, winning our class, we also got awarded the prestigious Phil Irving Trophy.

I can not thank Peter enough for all the excellent work and great advice over the years, he has developed this tz350 from an evil handling motorcycle into a proper grand prix bike which is a pleasure to ride fast.

Thank you Peter and Trish of Promecha

Bike lowering is done internally (front and rear) to maintain handling characteristics. How much a bike can be lowered before handling and safety become an issue is dependent on bike design and application. For info on your particular make and model call for advice on 03 9560 2770.

Note: The lowering process is reversible, should you wish to change it back in the future.

  Triumph Bonneville T100 Hold that ROAD  
  Bloody brilliant! The first thing you notice is of course that the bike doesn't slump on its rear springs like a cringing dog the moment you get on board.  
  Kawasaki 1200 ZXR PROJECT ZED  
  I've commented in previous tests.. that a suspension fiddle was on the must-do list. Well, it's now mission accomplished - and the transformation is impressive.  
  On the surface, the range of adjustability appears to allow individual owners to get a setting just right for them so why did we consider additional tuning?  
  Yamaha WR450 SPEED BUMPS  
  There are many variables in suspension sensitivity - rider weight, rider/bike weight, weight distribution, the addition of pillion passenger and luggage, and so on, and every adjustment you make affects another aspect of suspension performance.  
  Moto Guzzi California Stone SERIOUS SUSPENSION  
  It would seem most people find it hard to accept that their standard suspension and ride quality could be improved so much. Those who have ridden my bike are converts...
