DESCRIPTION

RK Performance RX-Ring GB520XSO chains are ideally applied for off-road driving thanks to the type ‘RX’ seal rings with four contact points, two zones for depositing lubricant and a stabilising reinforcement rib: this is an evolution of traditional X-rings, allowing for high resistance to heat and abrasion, and for chain life which is 30% longer compared to that of a corresponding round section, O-ring chain. Designed specially for cross-country, enduro, rally and supermotard motorbikes up to 800 cc, they are the best thing for your motobike.

Technical features:

RX-Ring – GB (gold-coloured external plates) – Links to be riveted (standard) – Joint links (optional)

Weight (120 MG): kg. 1.890

Chain maintenance:
final chain transmission is one of the most important components for motorbike and motorcyclist’s safety. This organ endures continual stress due to environmental agents and to heat, developed with high rotation speeds: only through continual controls and adequate maintenance can you attain the performances you expect from it in terms of reliability and of limited energy absorption. Visual inspection.
Check frequently:
smooth running of articulations (links must move freely); plates, rollers, pins and o-rings must not be damaged; o-rings, rollers, little springs of joint (if foreseen) must all be present; little spring of joint (if foreseen) must not be exceedingly worn out.
Control and resumption of tensioning:
first, we suggest you control and resume the correct degree of tension after the first 80-100 km of employment of your new chain, and, subsequently, every 300-400 km. Control is carried out after centre-lining the middles of: the pinion, the pin of the big fork, and the back wheel, and by verifying that the mean point of the lower part of the chain swings freely by about 10-15 mm.
Wear control:
1 – Submit upper part of chain to appropriate degree of tension.
2 – Detect chain length by measuring with a calliper or with a line – for 520, 525, 530 and 532 chains, a length of 16 links and check that it does not exceed 256.5 mm for chains without o-rings and 255 mm for chains with o-rings – for 415, 420 and 428 chains a length of 23 links and check that it does not exceed a 295 mm length for chains without o-rings and 293.5 mm for chains with o-rings.
3 – Correct measurement of stated number of links is carried out from centre of one pin to that of the 16th (or of the 23rd) subsequent pin, depending on the measure of chain.
4 – NOTE: modern chain manufacturing technologies have made old control procedures totally ineffective- procedures such as, e.g., measurement of side arrow, or, even worse, the side flapping test for the upper part of the chain, strongly beaten. Such systems make even a new chain look worn out
