Dr. Pulley Variomatic weight

25 x 15mm, set with 8 pieces
Are always delivered in sets for one vehicle. Lighter weights as standard weights = better acceleration; deviations from the standard weight do not according to RTR (StVZO)

Normal vario rolls wear out and flatten after some time at one or more points. This causes immediately an uneven acceleration. Those flattening's are integrated by Dr. Pulley. That's why they do not twist and therefore slip always at the same place and wear evenly. The result is an amazing, unprecedented ride quality and enhanced uniform acceleration without jerking. Excellent sliding properties on the aluminium variomatic material, as well as a significantly longer life thanks to the special self-lubricating polymer nylon material. No need of additional grease or lubricant. It is generally recommended by Dr. Pulley to use about 10-15% lighter rolls than the original. This proves a substantially stronger and steadier acceleration with constant high speed
