Tyres:
There seems to be a wide variety of tyres used on the 750R. Positive comments were received for the Pirellis "Very good", "Excellent in the wet" and the Avon AM22/23s "In the dry they transform the handling…" Continentals received a mostly favourable response "best tyres I've used on this bike", "I've covered 6000 miles and had no probs whatsoever and I reckon they will last another season too", "They seem okay in the wet and the dry", "…back end slid out in the wet" as did the Bridgestone BT45s "Great tyre loads of feel and grip", "They are excellent…", "good, but the softer compound wears quicker than I would expect, particularly on the front", "…solved all the handling problems", "grip on the bridgstones was fine stabilty was not". Michelin Macadams and Metzelers were also on the whole liked, but not by everyone.

Exhaust:
Some bikes are still using the genuine Kawasaki system, however most are running replacements. The Motad Nexxus 4-1 system seems to be the most popular and is on the whole praised for its build quality "Good quality system", "Looks good, sounds good, deep at low revs", however it does seem to be a little on the quiet side. Unlike the Micron 4-1 system "Very noisy but good fun and people sure hear you approaching" and the Yoshimura, which is described as making a "Loud hissing sound". The Laser 4-1 racing system is also mentioned "It sounds great but to replace the oil filter it all has to come off. This is a pain".

Brakes:
EBC pads seem to be the most widely used and the most popular, with the sintered pads in particular receiving praise.

Suspension:
A lot of bikes are running with the OE set-up, which when working is liked, however as the bikes age shot rear shocks and worn out anti-dive will make the bike "handle like a pig!". To sort things out Progressive fork springs are recommended, along with a Hagon rear shock "Good quality, but a pain to fit as you have to dismantle the rear sub-frame".

Other mods:
A wide-range here: Including braided hoses, progressive fork srings, anti-leak fork seals, k/n airfilter in airbox which inproved bottem end response, sports rack and replacement tinted screen. Handlebars from a 1984 GPZ900 Ninja give a ton more comfort, and stainless braided teflon lines from Goodridge are a must.
