SunL Hanma R6 — Poor quality product!
Purchased SUNL Hanma R6 December 22, 2007... Given as Christmas gift to 6 year old 54 pound (24.49 kg) grandson. He received gift on December 26th. The recommended inspection before riding was completed on December 24th per the checklist in the owners manual. In addition to pre-ride inspection all bolts and nuts were checked for tightness. One bolt was found missing in rear muffler hanger and a number of bolts were loose. The nuts that attach the muffler to the engine head were loose and also tightened. Lug nuts on wheels were also checked for proper torque.
During pre-ride inspection what looked to be a small crack was noted on rear rack bracket. Per instruction booklet motor break in procedures were followed by setting throttle at approximately half throttle for first ten hours. Youngster rode with father who was on a Kawasaki quad and father insured that engine speed was varied and that constant low speed was avoided However, unit was never broken in due to a total of ten hours not being completed. The vehicle held together only long enough for one tank of fuel and part of another tank to be used.
December 26th: Rear muffler bolt came loose and was lost. Bolt replaced. Rear rack bracket broke and rack went forward into plastic body housing breaking plastic body.
December 27th: Keeping muffler tight continued to be a problem and muffler was wired because muffler bracket broke. Battery case latching system broke.
December 28th: Chain came off and had to be replaced and retightened and muffler continued to work loose at engine head.
December 29th: Front rack mounting broke and bolts holding muffler on engine head came loose and were lost, this was the end of using the unit. Unit was returned to dealer on January 4th.
The unit is sold as an all terrain vehicle for off use road only. This unit was never subjected to any excess weight, nothing was carried on either rack, and the unit was never subjected to any severe treatment such as jumping or high speed operation in rough terrain, or for that matter even over mild terrain... Unit was operated in field and pasture conditions in a rural area. None of the areas would be considered extreme or severe terrain. Overall the unit was operated in what would be considered mild territory for any off road or all terrain vehicle.
The dealer has stated that the damage to the unit appeared to be “impact” damage. There was never any impact with any object other than those that were attached to the unit and fell off and impacted some other part of the unit such as the rear rack hitting the plastic body.
I have absolutely no complaints at all about the engine other than the muffler not staying on the unit. Engine started easily every time and ran excellent. Brakes worked well and transmission seemed to perform flawlessly. However, I would add that the unit has not operated the full 10 hours as recommended for break in.
The major problem I see is that the tubing used in the construction of the frame and racks is of extremely poor quality. With such little operating time under such mild conditions and seeing all of the welds break and other frame problems I am concerned that a major frame component could fail. Failure of a major part such as swing arm or other steering component could result in sever injury or even death to the rider and even low speeds. Don't waste your money, or chance your kids life.
