batzajla Objavljeno November 19, 2003 Avtor Opozori Objavljeno November 19, 2003 In the run up to the Milan show Aprilia were teasing us by telling us they were launching a "45.v2". We expecting a motocross bike with a development of Yamaha's 450cc single. Aprilia's boss Ivano Beggio has been hinting for some time that a return to off-road and dual purpose bikes was dear to his heart. What we got was not the bike, but the just the engine. And what a brave and significant move that engine is. V-twins aren't exactly common in motocross. Developed entirely in house, the 77° V-twin is amazingly compact. It's clearly smaller than many of it's single cylinder competitors. Whilst not actually revealing it's weight, Aprilia claim it's lighter too. With use of light weight materials such as magnesium for the covers and titanium for the eight valves, who are we to argue. The cylinders have a chain driven single cam. The alternator is big enough to drive an electronic fuel injection system, as well things like electric start. It's been reliably up to 14,000 rpm on the bench. It is also suitable for boring out to larger capacities. Aprilia say that the v-twin's lighter drive shaft and smaller bore and stroke reduces the inertia and gyroscopic effects, improving responsiveness and handling. There are no power figures available, but we think it could reach 70 bhp in some variants. They also say that this engine configuration is well positioned to stay ahead of future tightening noise and emission legislation. Something that could kill off some of the competition perhaps. The bike itself should be revealed in early 2004 for use in the FIM World Championship Motocross Series, and expect this engine to be used in a variety of off-road, dual purpose and even road bikes (in the RS250 frame to make a RSV450 for next year perhaps). The fact that this was an in-house project is significant, and shows that Aprilia have moved on from their Rotax days, and now have the capability to develop a complete range of engines of different configurations. Rumours that engineers have started work on triples have been doing the rounds of late, and with Laverda's triple heritage, at least one variant will be going there, with Aprilia holding onto others for their own models. Now howsabout putting two 45.v2 engines together to make a 900cc v-four.......Mmmmmm.

Noise Objavljeno November 20, 2003 Opozori Objavljeno November 20, 2003 Tole je beseilo o debiju... Aprilia ‘s debut in Supermoto World Championship began in SPA where, inside the historical car’s circuit a striking Supermotard track has been built up. A very technical track of 1250 m, 1100 of whom made of asphalt and 150 of pretty engaging off-road, with two jumps and two reverse curves on which raiders had to show their best. The weather was nice during the day and the sun showed up following the riders during every test session. Alex de Angelis and Aprilia’s SXV 4.5 debut in Superbike world championship was extremely positive. During the first free session Alex tested the bike and the track executing few exercises to determine what kind of tires and gear ratios use: his timing on the lap wasn’t bad at all, ending up 15 seconds behind the first. During the second session Alex worked on the brakes and on Aprilia’s set up gaining another improvement that brought him to 12 seconds of detachment from the best timing. In timed session Alex overcame himself ending up 8 seconds from the best timing thanks to an increased confidence with his motorbike. Alex said “ It’s so exciting to ride this revolutionary motorbike, it’s very easy and the twin engine has a lot of torque and power. If you think that I’m not a Supermoto professional rider and I’ve no habit with off road, I’m very happy of my best lap” The SXV 4.5 as well surprised for the reliability in this first race, without no previous test at all, performing more than one hour and a half without any technical problem.

Objavljeno November 20, 2003 Opozori Objavljeno November 20, 2003 ne vem, treba počakat na neodvisen test, zgleda pa fino, neki novega, samo serđo qualiti je pa aprilia še vedno motor bo sigurno težji, ker tudi 4 takt še vedno ne more prelahkirat 2-takt mašin, ima pa proti njemu druge kvalitete..upam da jih bo aprilia tut kej pokazala še zmeri pa je stvar racing in vzdrževanje 2 cilindrov je sigurno višje kot enega v vsakem primeru pa komej čakam kak pravi test, pa zvok me tut zanima
