SENDING YOUR BIKE  |  DISCLAIMER: THE FINE PRINT

INSPECTION AND DIAGNOSTICS
  • Preliminary measurements are taken and geometric angles of chassis components recorded. Measurements of frame, steering head/fork legs, subframe, and swing arm are made with a state-of-the-art digital protractor accurate to one tenth of one degree.
  • Measurements are noted on a detailed diagram (see illustration below) for our database before repairs are begun.
  • Steering head and bearings are disconnected and removed.
  • Bearings and races are inspected for damage and wear.
  • Bike is mounted and centered in MotoLiner frame measuring and alignment machine.
  • Centering gauge is set in frame’s steering head to check centerline and rake/caster angles.
  • Steering head angle is checked and measured with computerized digital protractor.
  • Swing arm and subframe are checked for misalignment.
  • Swing arm and rear suspension components are checked for play in bearings, bushings, and links.
  • Rear wheel is checked for run out.
  • Rear wheel is checked for alignment.
  • If any measurements are off, a straightening procedure is planned.

REPAIR PROCEDURES
By comparing this data to factory specifications, repairs are made with a series of fixtures, hydraulic jacks and screw jacks. With twenty years of experience and a lot of finesse, chassis components are carefully twisted back into place. TIG welding is used where appropriate.
After all chassis components are realigned, the new measurements are recorded in our database.
For different chassis attitude/pitch set ups, measurements are made and recorded, along with the effects they have on rake and caster. All recorded data is provided to customers on a frame diagram data sheet.
Upon customer request, steering head frame modifications for certain types of race conditions are available. Contact us to discuss your specific needs. (For off road use only.)
Note:
Due to repair procedures during steering head and swing arm realigned, bearings and races sometimes need to be replaced before repairs can be completed. And there is always the possibility of secondary damage, depending on the severity of the original damage. This is sometimes unavoidable during repair procedures.
Also, additional costs may be incurred due to fixtures that may need to be fabricated for a specific model.
